It should be pointed out that the laser weapons that the US Army and Navy are advancing to actual combat are mainly fiber laser pointer weapons. This is similar to the technology used by the Air Force in the previous report, and its technology is relatively mature. The so-called fiber laser is a laser that uses fiber as the laser gain medium. It is a type of solid-state laser. It has relatively good beam quality, ultra-high conversion efficiency, completely maintenance-free, high stability, small size, good heat dissipation, and shape. Easy, distributed installation, strong environmental adaptability and other advantages.
Theoretical analysis believes that the output power of a fiber laser is limited, and a single fiber generally cannot exceed 10 kilowatts, otherwise the power is too large, and a large number of photons entering the fiber will cause it to heat up quickly, and it is difficult to dissipate the fiber in time. The Lockheed Martin multi-kilowatt fiber green laser pointer uses the “spectral beam combination” technology to combine the beams output by several fiber lasers to form a high-energy laser beam, thereby developing a high-power of 60 kilowatts Laser weapon system.
Loading laser weapons on aircraft is systems engineering. It should be said that multi-kilowatt fiber lasers are currently one of the more mature laser weapon technologies. So, is there a similar technology in China now? Upon review, a previous report from this newspaper pointed out that a scientific research team of the former General Equipment Department used multiple independent Laser Engraver to form a composite resonant cavity with the unique “self-collimation, mutual injection, and adaptive” characteristics of the pyramid. “High power, high energy, high brightness, multifunctional” laser output.
