    Default german military laser artillery

    Hi, this could be the laser pulse cannon we are all dreaming of ;-)
    Probably not shooting colors but maybe they include color beams for targetting like with gunfire it sometimes lights up or more advanced tracking and targetting, i don't know what hit us but there is a hole in the plane

    A German company has brought us one step closer to the kinds of shootouts only seen in Sci-Fi films. Düsseldorf-based Rheinmetall Defense recently tested a 50kW, high-energy laser at their proving ground facility in Switzerland. According to the company, the laser passed the test with “flying colours.”

    The system isn’t actually a single laser but two laser modules mounted onto Revolver Gun air defense turrets made by Oerlikon and attached to additional power modules. The laser modules are 30 kW and 20 kW, but a Beam Superimposing Technology (BST) combines two lasers to focus in a “superimposed, cumulative manner” that wreaks havoc on its targets.

    First, the system sliced through a 15mm- (~0.6 inches) thick steel girder from a kilometer away. Then, from a distance of two kilometers, it shot down a handful of drones as they nose-dived toward the surface at 50 meters per second. The laser’s radar, a widely used system called Skyguard, was capable of tracking the drones through their descent up to three kilometers away.


    After successfully testing their 50kW laser system, Rheinmetall Defense has its sights on a truck-mounted mobile system with 100kW of metal-slicing power.
    For its finale, the laser’s ability to track a very small ballistic target was demonstrated. It honed in on and destroyed a steel ball 82mm in diameter traveling at 50 meters per second. The small ball was meant to simulate an incoming mortar round. Rheinmetall says their laser will reduce the time required for C-RAM – Counter Rocket, Artillery, and Mortar measures – to a matter of seconds, even in adverse weather conditions. In fact, weather at the Ochsenboden Proving Ground in Switzerland where the demonstration was carried out included ice, rain, snow, and extremely bright sunlight – far from ideal.

    Rheinmetall had tested a 10kW high-energy laser last year. Next year the company plans on testing a 60kW “technology demonstrator.” In addition to the more powerful laser, the system will be packing 35mm Ahead Revolver Guns. With the combined systems Rheinmetall hopes to explore ways in which a laser and an automatic cannon can be used together. And the company is already looking past the 60kW, saying in a press release that “nothing stands in the way of a future [high-energy laser] weapon system with a 100kW output.” Lastly, they’ll begin making these high-energy laser systems mobile by mounting a laser onto a TM170 armored vehicle. Their ultimate goal is to mount the lasers on vehicles operating in the open.

    While minuscule compared to the 200 petawatts of laser power (ten to the fifteenth watts!) that scientists in Europe plan to use for experiments, the 50kW laser seems quite ready to make a difference on the battlefield. Apart from science fiction novels, the idea of using high-energy lasers have been considered for weaponry since the mid 20th century. Countries such as the US, Russia, China, among others, are developing their own high-energy laser programs. Whether or not we hear about future demonstrations will be a matter of national security rather than technological success. I think it’s safe to assume this is one arms race that’s soon to heat up.

    What if the drones where built with highly reflecting material capable of handling 50kW pulses?

    My thoughts as well. Potential responses could include development of lasers with dynamically and rapidly tunable wavelength, or developing x-ray (or at least EUV) lasers (for which there is no known reflective material that works at low angles of incidence.) Or just dispense with lasers, and instead design particle guns or rapid-fire small-caliber railguns...

    I suspect that these weapons are developed by scientists purely as an excuse to play with big powerful lasers.

    Imagine what one drop of bird-poo on the output aperture would do ?
    If you know what dessert-dust can do to a swiss-watch, image what it does to a 100kW laser !

    Slicing steal at 2km, yeah right ! What do you think a goalkeeper or a phalanx would do to a drone ?

    Probably that the wavefront of that laser beam at 2km have to be flat!... Wich mean they probably would have to use a deformable mirror array just like they do on big powerfull telescope to preserve the beam quality

    I guess that to avoid dust problem on their output exposed optic, they use positive air pressure blast like for the laser cutting table.

    I remember the American already made these kind of laser but they was chemical laser... Also remember the Airbone laser few years ago?... just like in the Real Genious movie) =)

    Eh, shhhhhh, keep your voice down!
    We don't want our secrets to get known! If the government finds out, our budgets would be cut before anyone can say "megawatt"!

    That has always been my STORY

    Yes, that is likely even if they are using disc or fiber in the 1-2 um wavelength. But these systems for the small beams of laser projectors are not exotic and there are a few commercial manufacturers that build them. So, you can buy them yourself; they are in the 10-50K + range.

    I love this.

    Great solution. If you want to be a sitting duck for radar guided missiles....

    Lockheed Martin has a similar weapon I believe.

    Tracking systems still look like they are in testing phase from this video - otherwise this weapon would only be useful against......a train.
