Fighting fiber laser for the US Army

61
As the "Lenta.RU", the command of the American army signed a contract with Lockheed Martin, providing for the development and production of combat fiber laser power 60 kilowatts. In the future, like weapon will be used to destroy unguided rockets, mortar shells, artillery shells and unmanned aerial vehicles.


A new laser facility is being integrated into the HEL MD experimental platform (mobile high-energy laser demonstrator. ”According to company representatives, the facility will be equipped with several fiber lasers to produce a high-power beam using spectral alignment technology.

So far these are all details about the development of a promising 60-kilowatt fiber laser.

It should be noted that the presentation of the technology of spectral alignment of fiber lasers was held in January 2014. Then the company Lockheed Martin demonstrated laser power 30 kilowatts, which used several generators. Optical fiber was used to transmit rays to a special combining device.

In the new installation, each laser beam will have a different wavelength. The device combines laser beams from various optical lines into one powerful high-quality beam. It is noted that the company's specialists managed to reduce energy consumption by 50% compared to solid-state lasers.

      For every trick we have a bolt with a left-hand thread - for each weapon a corresponding "antidote" is being developed very quickly - here most likely it will be a smoke generator or something similar on a rocket - to scatter the beam. A beam is not a shell for you - you don't need armor ...

            The laser pointer does not need to burn the target. Therefore, it is important there that the beam simply reaches the object, and not carries all its energy to it.

            Protection: in addition to the mirror surface, it is easy to apply the rotation of the rocket around its axis and the ablation coating. If such a coating on the spacecraft descent device saves the device for 10-15 minutes of descent at several thousand degrees, then during this time the rocket will certainly reach the target or leave the laser efficiency zone.

              The trajectories of the descent vehicle and the warhead are somewhat different, therefore, the speeds are different, and the heating temperatures, too.

        And now some calculations (from the site of KB "Khimavtomatika")
        The wavelength of a carbon dioxide laser is known exactly - 10,6 microns. The size of the output aperture of the radiator can be “by eye” defined in 15, see. This, by the way, is an excellent result - usually the dimensions of the active zone of gas-dynamic lasers are measured in units of centimeters. Further simple arithmetic shows that already at a distance in 10 km the base of the radiation cone will have (at best, with a divergence equal to the diffraction) diameter in 1,5 m and area in 18 thousand square meters. cm. At a distance in 100 km - 15 m in diameter and 1,8 million square meters. cm square. It is on this huge “spot” that 100 KW of laser output power will be spread.


        At a distance in 100 km, the power density in 0,06 W per square meter is obtained. see. Such a "sizzling beam" can be obtained from a flashlight. At a distance of 10 km, 5,6 W per square meter is obtained. see. This is already quite noticeable - but we need not to warm up, but to break the design of the enemy’s aircraft or cruise missile. There are various estimates of the thermal energy required to destroy a target; they all fall within the range from 1 to 20 KJ per square meter. cm.


        For example, for the complete evaporation of 1 sq. cm sheet of 3 mm thick need to be “pumped” into it 8 – 10 KJ. The bullet on departure from the barrel AKM carries about 4,4 KJ per square. see. But even the smallest of the mentioned figures (1 KJ) means that laser “shooting” at a distance of 10 km will require holding the radiation spot on the target for 160 seconds. During this time, the subsonic cruise missile will fly 45 km - unless it is shot down on the way from the good old ShKAS.

            Self-propelled laser system (SLK) 1K17 "Compression"
            In the early 1990s, a prototype of a mobile laser gun was assembled in our country, which was deployed on the basis of the Msta-S self-propelled guns. The project received the designation 1K17 “Compression”. The basis of this unique complex was a multi-channel solid-state laser. According to unconfirmed information, an artificial cylindrical ruby ​​crystal with a total mass of 30 kg was specially grown for the Compression plant. According to another version, yttrium aluminum garnet, in which neodymium was added, could serve as the laser body.

            Self-propelled laser complex (SLK) 1K17 "Compression" was ready in 1992 year. Its main purpose is to fight a potential adversary with optical-electronic devices. It used a multichannel laser. There were a total of 12 optical channels (2 series of lenses), each of which had an individual guidance system. The use of a multichannel scheme allowed us to perform multi-band SLK. As a counter to such systems, the adversary could try to protect the optics by installing light filters that would block the radiation of a certain frequency. However, against simultaneous damage by laser beams having different wavelengths, light filters are useless.

            Moreover, the main problem of any laser today is their very low efficiency. Even in the most complex and most advanced installations, it reaches only 20%. Installation "eats" a lot of electricity. For this reason, high-power generators and an auxiliary power unit (APU) occupied most of the increased cabin of the Msta-S self-propelled guns (which was rather big in itself), on the basis of which the Compression Complex was located.
            Unfortunately, everything turned off with the collapse of the USSR

          A research team at the College of Engineering and Applied Sciences at Princeton University (USA) has discovered and investigated a new mechanism for generating coherent (laser) radiation. The discovery was made almost by accident.

          Studying the properties of a semiconductor cascade laser, scientists recorded the phenomenon of their generation of a second beam of photons slightly less than the main beam of energy. Such radiation was distinguished by a number of interesting properties. In particular, the same power value was achieved at a lower current value than the main beam.

          The laser could operate at higher temperatures, and was characterized by higher temperature stability. It is expected that new lasers will be able to operate at higher temperatures than existing analogues, which will expand their scope.

          That was in 2009. In five years, much could have changed.

          And this is still without taking into account losses due to heating of the atmosphere during the passage of the beam, a change in the divergence of the beam for the same reason, for a subsonic rocket, there is also cooling of the rocket's body from airflow. And if you give the surface the character of corner reflectors, as in all known reflectors ... Or slow rotation in the longitudinal axis. Yes, with an ablative coating ...

          I completely agree ! It is also necessary to take into account atmospheric interference. The creator of the laser, when he was closing the topic of research on combat lasers, said that he was completely sure that no one could create a combat laser (working to destroy a target) that worked normally in the atmosphere.

            Why polish? Do you want to return the beam to the emitter?
            The task is to dispel! It can be any rough, rough but reflective surface (foil, spraying, coloring).
            And if spot heating is prevented by rotation, uneven movement or rocking, then the thermal effect will spread across the surface and in time, which will prevent destruction.

    As I understand it, the idea is something like this. Use a laser property such as rate of fire. I mean, there are no moving parts for firing a shot, so theoretically the speed is close to light. This, of course, is not so, but still shooting with the help of powder charges rests. So we raise the laser power and data processing speed, after which we try to bring down the enemy’s charge somewhere at a distance of up to a kilometer. No, somehow it’s weak anyway, warming is still long ...
    But against drones, at least modern ones, that's not bad! Against many small, cheap and obnoxious drones. Against a whole cloud of nimble, "smart" and equipped with small explosive charges. Exploding on periscopes. Rubbing into the viewing slots. Striving to tear off the officer's head with an explosion. I don't know about lasers, but some conclusions can be drawn about the direction of the most promising American research.

    Lasers must be developed in our country. Lasers from fiction have become very serious instruments today. Actually, your computer has a laser, and it cuts exactly the mirror surface of the disk. So the mirror surface is not a panacea. Smoke will weaken a little but not quite. Well, you also heard about the green laser. Even on the page of this forum offers to buy it pop up. So already at a distance of 2 km it poses a serious problem for vision, do you remember the attacks on landing aircraft? Does he have food? Well, not a gas generator.

    So far, the laser is only effective against optical guidance systems.
    It takes a lot of energy to create order out of chaos. For application under atmospheric conditions, other spectral (gamma, X-ray) and energy characteristics are needed. Below are excerpts from the article (there is also a video)

    High Power Laser Testing

    The above demonstration tests did not really include shooting a real mortar shot, but rather something that could very accurately reproduce the physical and ballistic characteristics of this type of weapon in shape. These were steel balls 82 mm in diameter, shot from a pipe with compressed air and filled with explosives so that they could be seen from a great distance. For the same reason, a small explosive charge was installed in the bow of jet drones (and in fact Chinese radio-controlled models of the Hawk attack aircraft).
