D_ME-SHORAD_50_kW_laser_weapon_Stryker_8x8_armored_vehicle_United_States_details_925_002.jpg

The Stryker A1 with the 50-kilowatt laser weapon provides a low cost-per-engagement Maneuver – Short Range Air Defense (M-SHORAD) system. It protects maneuvering forces from rocket, artillery and mortar; unmanned aerial system, and fixed- and rotary-wing manned aircraft. It also gives soldiers an effective counter-UAS system as well as provides counterintelligence, surveillance, and reconnaissance capabilities. The radar on the DE M-SHORAD detects an enemy drone about 8 kilometers in the distance. The laser locks onto the drone, tracking it as it moves closer to the vehicle. When the DE M-SHORAD detects incoming mortar fire, the laser quickly moves to intercept the incoming rounds and fires, instantaneously sending heated energy at the round, which is destroyed in seconds. The laser then returns to the drone, destroying it several seconds later.

The DE M-SHORAD 50kW-class laser is powered by high-capacity batteries that are charged by Stryker’s diesel engine. The vehicle is also fitted with Battle Management System and computerized communication system including manual/semi-automatic/ automatic target acquisition, aim-point selection, and aim-point management systems connected to the U.S. Army battle management system. The acquisition and tracking sensors consist of Infrared-based wide field-of-view (FOV) components for target acquisition and IR-based narrow FOV fine target tracker. Standard equipment also includes thermal management systems that control laser cooling systems and standard heating, venting, and air conditioning for all other subsystems.

Laitan tänne. Kyseessä on kuitenkin mullistus, sillä aikaisemmin meillä ei ollut teknologiaa joka käyttäytyi siten että mitä enemmän energiaa varastoidaan "säilöön," niin sitä nopeammaksi se tulee. Gaussiaseille ja lasereille tämä on hoosiannaa. Käänteisenä tämän voi myös nähdä siten että laukausmäärien tullessa tappiin, aika laukausten välillä pitenee kun systeemi yrittää saada varauksen aikaan.

Quantum physics can often make an object behave in seemingly impossible ways, such as tunneling through barriers as if they were not there or seemingly existing in two or more places at the same time. Now scientists have used quantum physics to create a battery capable of "superabsorption," meaning it absorbs energy more quickly the bigger it gets.

Previous work found that matter could act collectively in surprising ways due to quantum physics. For example, in "superradiance," a group of atoms charged up with energy can release a far more intense pulse of light than they could individually.

In the past decade, researchers have also discovered the reverse of superradiance was possible—superabsorption, with atoms cooperating to display enhanced absorption. However, until now superabsorption was only seen for small numbers of atoms.

Now scientists have developed a superabsorbent "quantum battery" that requires less charging time the larger it gets.

"The potential applications are the development of new types of batteries that can charge faster," says study lead author James Quach, a theoretical physicist at the University of Adelaide in Australia. "In the same way that there has been a lot of recent investment in quantum computing—that is, using quantum effects to make computing faster—other operations about transferring energy or even harvesting energy can in principle be made faster by using quantum effects."
 
The Air Force Research Laboratory's Directed Energy Directorate hosted a collaborative wargame with its sister AFRL unit, the Munitions Directorate, at Kirtland AFB, Jan. 24-28, 2022. The Directed Energy and Kinetic Energy Directed Energy Utility Concept Experiment, or DEKE DEUCE, explored synergies between directed energy and kinetic concepts in the future battlespace.

"DEKE DEUCE required extensive collaboration between dozens of scientists and engineers from both directorates over a period of more than nine months," said Dr. Darl Lewis, the DEUCE lead and wargaming principal investigator. "The Office of Naval Research also collaborated extensively in the lead-up to playing their Elektra battle management concept alongside those of AFRL."

DEKE DEUCE placed pilots, weapon systems officers and air battle managers in a series of virtual vignettes exploring mission sets that relate to the combined use of DE and KE systems, tying together previous studies and analysis focused on an airborne high energy laser pod and two future kinetic concepts.

"An urgent need exists to rapidly field and integrate viable next-generation weapons, both DE and KE, in response to increasing capabilities and aggressive intentions from our adversaries," said Lewis. "This DEUCE focused on identifying capability and joint integration gaps that can be addressed by systems under consideration, as well as potential future tactics and procedures."
 
Northrop Grumman has been in talks with the Pentagon and the military services on a modular approach to building laser weapons that could engage a greater number of suppliers.

The Defense Department is considering a modular open-system approach, or MOSA, and sent the company a request for information in October. Donna Howland, Northrop’s business development director for directed energy, told Defense News that the approach would allow some companies to specialize in laser generation and beam control, while others focus on the cooling module, the batteries and the fire control subsystem.

MOSA “will allow for an expanded supplier base and makes the whole directed-energy market more healthy, as the MOSA architecture allows for the government to decouple the subsystems from the full system architecture,” she said in a March 31 interview.
 
The laser, dubbed the “Iron Beam,” successfully intercepted unmanned aerial vehicles, mortars, rockets, and anti-tank missiles in multiple scenarios, the defense ministry said.
Rafael first revealed in March this year it had received the defense ministry’s approval to proceed with the development and production of an operational high-power laser system.
The two sides signed a multi-million dollar contract in the same month. The contract signing took place after the company first unveiled the Iron Beam concept in 2014.

Although there's no plan to field the LLD, it offers a glimpse into the future of laser weapons. It is compact and powerful, yet more efficient than previous systems. It has specialized optics to observe a target and focus laser beams to maximum effect, while also incorporating artificial intelligence to improve tracking and targeting.

"LLD is an example of what a very advanced laser system can do to defeat significant threats to naval forces," said David Kiel, a former Navy captain who is a program officer in ONR's Aviation, Force Projection and Integrated Defense Department, which managed the testing. "And we have ongoing efforts, both at ONR and in other Navy programs, to keep building on these results in the near future."

During the recent test at White Sands, the LLD tracked or shot down an array of targets-including unmanned fixed-wing aerial vehicles, quadcopters and high-speed drones representative of subsonic cruise missiles.

"We're proud to say that the Layered Laser Defense system defeated a surrogate cruise missile threat in partnership with the Navy, White Sands Missile Range and Army High Energy Laser Systems Test Facility teams. Lockheed Martin drew best-in-class laser weapon subsystems from across the corporation, including key industry partner Rolls Royce, to support the entire threat engagement timeline from target detection to defeat," said Rick Cordaro, vice president, Lockheed Martin Advanced Product Solutions. "We leveraged more than 40 years of directed energy experience to create new capabilities that support the 21st century warfighter."

Dr. Frank Peterkin, ONR's directed energy portfolio manager, said, "The Navy performed similar tests during the 1980s but with chemical-based laser technologies that presented significant logistics barriers for fielding in an operational environment. And, ultimately, those types of lasers did not transition to the fleet or any other Service.

"Today, ONR coordinates closely with the Navy's resourcing and acquisition communities to make sure we develop laser weapon technologies that make sense for the Navy's requirements to defend the fleet and for operations in the rough maritime environment at sea," Peterkin continued. "It's a challenging problem, but Navy leadership at all levels see potential for laser weapons to really make a difference. The next few years are going to be very exciting as we work with the Navy and joint partners to make the capability we just saw demonstrated by the LLD a reality for the naval warfighter."
 
Twiitissä sanotaan että 'scifi' mutta hämmästyttävän hitaasti tämäntyyppisiä aseita on saatu käyttöön. Jo 70-luvulla tehtiin ensimmäisiä menestyksekkäitä koeammuntoja lennokkimaaleihin. USAn laivastohan on koekäyttänyt tämmöistä laitetta jo jonkun aikaa, mitenhän tämä vertautuu siihen?

1970-luvulla ammuttiin TOW-ohjus alas ja 1980-luvun alussa Sidewindereitä. Nämä laserit olivat kemiallisia lasereita. Jo 1980-luvulla niiden teho oli megawattiluokkaa. Tällaiset laserit olivat kuitenkin epäkäytännöllisiä. Polttoaine oli myrkyllistä, laukauksen hinta melko suuri ja laser vaati välillä jäähdyttelyä. Seuraavaksi tutkittiin vapaaelektronilaseria varsinkin ballististen ohjusten torjuntaan Laivasto kehitteli myös alukseen sopivaa mallia. Tämä lasertyyppi vaatii eräänlaisen hiukkaskiihdyttimen joten se ei ole oikein kenttäkelpoinen. Nykyään jenkeillä on jo palveluskäytössä Strykerin alustalle asennettu kuitulaser. Ne ovat olleet jo Viron puolella harjoituksessa.
 
The laser testbed serves not only as a technology demonstrator laser weapon but also as the basis for future R&D work at Unterlüß in Lower Saxony. It is designed so that all components of a future laser weapon system can be examined modularly. Every interface to the sensors – the radar, for example – or to the energy supply and laser source are “open” designs. This makes it possible to test every conceivable combination iteratively and then compare the results.

The objective of current studies in the laser testbed is to produce a suitable configuration for a mobile technology demonstrator with a laser output of over 10 kW for integration into a Boxer fighting vehicle by the end of 2022.

At present, the laser testbed consists entirely of subassemblies made by Rheinmetall. But open interface architecture makes it possible to integrate and test components from other manufacturers also.

The laser testbed consists of a 20-foot container divided into three compartments: laser, operator and infrastructure. Encompassing five 2 kW-fibre laser modules, the laser source is installed in the laser compartment. Bundled via spectral coupling, the individual laser modules achieve a total output of 10 kW, producing excellent beam quality. The rough orientation of the laser weapon station is based on data from the suite of electro-optical sensors in the weapon station. This is ready to operate around the clock. For fine tracking, the reflection of the target irradiated by the illumination laser is evaluated in the beam guidance system and transformed into corresponding guidance signals for tracking the target. Furthermore, under conditions of functional safety, all subassemblies necessary for target engagement, e.g., beam status monitoring and target point control, were achieved for the first time within the optical beam path.

During the C-UAS campaign conducted in Unterlüß, a variety of drone types were optically tracked and neutralized at ranges of engagement of up to one kilometer.

The results obtained were more than satisfactory. A demonstration was subsequently carried out in compliance with corona safety measures at Unterlüß for representatives of the Federal Ministry of Defence and the Federal Office for Bundeswehr Equipment, Information Technology and In-service Support. The outcome met the expectations of all participants.
 
Onkohan tästä venäläisten mainitsemasta 'Zadira' laserista tippunut mitään tietoa? En muista ainakaan nähneeni kuvaa (jos laite on rintamalla, venäläiset eivät ehkä halua näyttää ukrainalaisille millainen kampe se on). Uutisessa taidettiin mainita että se tarvitsee viisi sekuntia dronen polttamiseen, mikä on aika pitkä aika, joten kovin tehokas se ei taida olla.
Neuvostoliitollahan oli aikoinaan aika paljonkin erilaisia laserase-projekteja.

Ei ole mitään muuta virallista kuin uutismedia. 10 sekuntia voi olla alitehoinen taikka säde on levinnyt liikaa vaikka ne pumppaa energiaa siihen. Vaikea tietää kun ei ole nähnyt vehjettä, speksejä taikka käyttövideoita.
 
A team of physicists from the University of Amsterdam has now managed to solve the difficult problem of creating a continuous Bose-Einstein Condensate. Florian Schreck, the team leader, explains what the trick was. "In previous experiments, the gradual cooling of atoms was all done in one place. In our setup, we decided to spread the cooling steps not over time, but in space: we make the atoms move while they progress through consecutive cooling steps. In the end, ultracold atoms arrive at the heart of the experiment, where they can be used to form coherent matter waves in a BEC. But while these atoms are being used, new atoms are already on their way to replenish the BEC. In this way we can keep the process going - essentially forever."

While the underlying idea was relatively simple, carrying it out was certainly not. Chun-Chia Chen, first author of the publication in Nature, recalls: "Already in 2012, the team - then still in Innsbruck - realized a technique that allowed a BEC to be protected from laser cooling light, enabling for the first time laser cooling all the way down to the degenerate state needed for coherent waves. While this was a critical first step towards the long-held challenge of constructing a continuous atom laser, it was also clear that a dedicated machine would be needed to take it further.

"On moving to Amsterdam in 2013, we began with a leap of faith, borrowed funds, an empty room and a team entirely funded by personal grants. Six years later, in the early hours of Christmas morning 2019, the experiment was finally on the verge of working. We had the idea of adding an extra laser beam to solve a last technical difficulty, and instantly every image we took showed a BEC, the first continuous-wave BEC."

Having tackled the long-standing open problem of creating a continuous Bose-Einstein Condensate, the researchers have now set their minds on the next goal: using the laser to create a stable output beam of matter. Once their lasers can not only operate forever but can also produce stable beams, nothing stands in the way of technical applications anymore, and matter lasers may start to play an equally important role in technology as ordinary lasers currently do.


Materia laaseri, tässä pitää muistaa se fakta että photoni on se yksinkertaisin ja heikoin valon esiintymismuoto. Materialaseri on siitä kovempi muoto.

P-HEL
The Army Rapid Capabilities and Critical Technologies Office, in support of the Joint Counter-small Unmanned Aircraft Systems Office, continues to develop and test counter-small unmanned aircraft system prototypes like the palletized high energy laser, or P-HEL, with the support of YPG. “The laser, as part of a necessary layered set of capabilities against threat unmanned aerial systems, has tremendous potential,” said Maj. Gen. Kenneth Kamper who took part in live prototype testing of counter-small unmanned aircraft Systems at YPG in April. “There’s no doubt lasers will be on the future large scale ground combat battlefield, so it’s great to see these initial prototypes to gain understanding of its capabilities and think through where these capabilities will fit into our organization, impact how we fight, and understand how we need to adjust our doctrine.”

Packed with cameras, passive sensors, 3D detection, radar, optical systems, as well as tracking capabilities, the P-HEL is one of several prototypes that allows a commander and gunner to attack a drone or target with the laser. The system relies on high-powered energy to destroy its target instead of using traditional ammunition to shoot it out of the sky.

While the test-system itself is multifaceted so is the process for shooting a high energy laser at YPG, according to Test Officer Riley Sinek. “The P-HEL took the [Joint Counter-small Unmanned Aircraft Systems] program office, the [Rapid Capabilities and Critical Technologies Office] program office, YPG, the Federal Aviation Administration and the Laser Clearing House all to make sure one test can function safely and successfully,” Sinek explained.
From a test officer perspective, Sinek said its important they make sure the laser is leaving the atmosphere at 60,000 feet, in coordination with the FAA to ensure the laser energy is leaving above public airspace and “keeping our pilots and public air traffic safe.”

The geodetics support group works to conduct analysis needed for high powered laser tests. Using geodetic surveys — land surveys that account for the curvature of the Earth — they can ensure lasers are leaving the airspace at the minimum requirement.

While working with lasers has its hazards, one hazard in particular a test officer must consider is when the laser beam is fired. “As the beam diverges the power density in the beam size will eventually get to a less hazardous level but essentially the energy is going to continue until it hits something,” Sinek said.
 
The U.S. Navy and Air Force research laboratories are wrapping up a five-year joint effort to advance high-power microwave technology this summer with two months of testing in California.

The High-Powered Joint Electromagnetic Non-Kinetic Strike Weapon, known as HiJENKS, uses microwave technology to disable an adversary’s electronic systems. The Air Force Research Laboratory and the Office of Naval Research are conducting the capstone tests at Naval Air Station China Lake.

HiJENKS is the successor to the AFRL’s Counter-electronics High-Power Microwave Advanced Missile Project, which completed testing a decade ago. Jeffry Heggemeier, chief of AFRL’s high-power electromagnetics division, told reporters during a June 24 visit to the lab’s Directed Energy Directorate at Kirtland Air Force Base in New Mexico the program builds on CHAMP, taking advantage of new technology that allows for a smaller system equipped for a more rugged environment.

Heggemeier said the program hasn’t yet designated a platform for the weapon, but noted HiJENKS’ smaller footprint means it could be integrated on a wider range of carrier systems.
 
Northrop Grumman Corporation (NYSE: NOC) recently completed the preliminary design review for a high-energy laser prototype that will feature an architecture scalable to more than a megawatt for the U.S. Department of Defense. The review establishes the company's technical approach for precise, low-cost, speed-of-light technology for military operations.

"This is an important step in the ability to combine high-power laser beams into a single beam that can be scaled for maximum power," said Robert Fleming, vice president and general manager, strategic space systems, Northrop Grumman. "We're on track to demonstrate the technology, leveraging our decades of experience in the field."

In March 2021, the U.S. Department of Defense awarded Northrop Grumman a $72 million contract under the High Energy Laser Scaling Initiative (HELSI) to demonstrate a high-energy laser prototype using Northrop Grumman's coherent beam combining technology.

The company will test the prototype at progressively higher powers later this year to prove the coherent beam combining design

One roadblock to shrinking present-day electronics is the relatively large size of their capacitors. Now scientists have developed new "superlattices" that might help build capacitors as small as one-hundredth the size of conventional ones.

Whereas batteries store energy in chemical form, capacitors store energy in an electric field. Batteries typically possess greater energy densities than capacitors—they can store more energy for their weight. However, capacitors usually have greater power densities than batteries—they charge and discharge more quickly. This makes capacitors useful for applications involving pulses of power.

Since capacitor energy density is somewhat low, they are difficult to miniaturize. Antiferroelectric materials could help solve this problem. Like magnets, which possess north and south poles, electric charges within materials become separated into positive and negative poles. Antiferroelectrics are materials in which these "electric dipoles" are generally oriented in opposing directions, leading to an overall zero electric polarization. However, when antiferroelectrics are exposed to a strong enough electric field, they can switch to become highly polarized, resulting in large energy densities.

"Capacitors made out of antiferroelectrics could be much smaller than conventional ones, which would help to miniaturize electronic circuitry," says Hugo Aramberri, a materials physicist at the Luxembourg Institute of Science and Technology.
 
The U.S. Army opened the doors of a one-stop-shop for development and integration of directed energy capabilities at Redstone Arsenal in Huntsville, Alabama, last week as the Space and Missile Defense Symposium kicked off.

The Directed Energy Systems Integration Laboratory, or DESIL, will help speed up and streamline laser weapons research and development as the Army seeks to incorporate the technology into combat systems.

Simulation, component and subsystem testing, and verification and validation of overall systems can all be done in one lab at one location, Lt. Gen. Dan Karbler, the Army’s Space and Missile Defense Command commander told Defense News in an interview at the SMD Symposium. The lab’s capabilities will help reduce technical and schedule risk for programs.

And it’s not just a lab. Beyond two huge garage doors is a 400-meter outdoor range with an enormous mound of earth at one end which will serve as a test range. The large earth mound at the end of the range serves as a backstop to absorb the laser energy in testing.
Some of the capabilities that allow for indoor laser testing include the Robust Electric Laser Initiative that is capable of multi-kilowatt firing and helps prepare the lab to ensure laser instrumentation is ready.

The Army’s lab also houses a system called SMASH – or Small Measurement and Analysis System for High-energy laser systems. “SMASH measures the thermal properties and optics effects after the laser is fired for a short period of time,” Olbricht said. “From the results delivered from the shot profile, SMASH analysis can create a basis of beam quality.”

Another key piece of equipment in the lab is the High Power Laser Beam Dump, which absorbs “extremely high amounts of energy for a long period of time,” Olbricht said.

The system includes components capable of circulating 120 gallons of water per minute. The water is heated through the laser firing process and returns to a water tank through a closed-loop system that cools the water and purifies it through reverse osmosis. Impurities in the water can “lead to catastrophic events for the system during laser tests,” Olbricht explained.

The lab was constructed as a minor military construction project, costing less than $6 million to build, an Army spokesperson told Defense News.

The lab will be sustained “on a reimbursable basis in that the Directed Energy programs and related organizations pay a small reimbursable use fee to utilize the capabilities when required,” the spokesperson added.
