Fiber lasers refer to lasers that use rare-earth-doped glass fibers as gain media. Fiber laser pointer can be developed on the basis of fiber amplifiers: high power density is easily formed in the fiber under the action of pump light, resulting in laser working material. The energy level “number inversion” can form laser oscillation output when a positive feedback loop (to form a resonant cavity) is properly added.
In 1988, invented a double-clad fiber laser with rare earth doped erbium, and described its basic working principle. This fiber laser is small in size and high in energy conversion efficiency, up to 70%. The biggest advantage is that it almost does not require a cooling system. After fiber laser was invented, it was quickly commercialized.
Kotos has adopted 6 5-kilowatt fiber lasers produced by IPG to achieve a total output power of 32 kilowatts. In order to achieve high-energy focusing, the previous laser weapon solutions require beam coherent combining and other technologies. Laser action brings a lot of trouble. In order to reduce the complexity of the system, the Rouss solution directly overcomes this seemingly difficult problem. As mentioned earlier, the fiber laser is small in size. Simply put the 6 fiber lasers close together, and solved the problem very cleverly.
The Navy used a defense system test and successfully destroyed a motorboat 1 mile away. In August 2012, on the island of St. Nicholas off the coast of California, the Routh system successfully shot down an unmanned drone in its first maritime target test. In the subsequent tests, the unmanned drone was shot down four times, with a maximum distance of about 4 kilometers. The usual process is to use a low-energy green laser pointer to achieve stable tracking, and then launch a high-energy laser, and the down can be achieved in about 2 seconds.
At present, the Routh system installed on the Pons is still undergoing tests. The other party claimed that the system far exceeded expectations. Compared with the missiles that cost millions of dollars each, the sequential launch cost only 59 cents. The system did not work under severe sandstorm conditions, because the reorganization conditions were not suitable for the system, because the military believed that the attackers would not rush to attack under such harsh conditions.
