Abstract
In order to meet the application requirements of high performance, high safety and high reliability of laser explosives in future weapons and equipment, this paper tries to solve the problem of interaction reliability between laser and energetic materials, and studies the interaction law between fiber laser and energetic materials with high beam quality. The principle prototype of all-fiber laser ignition with high beam quality is developed. The interaction between high beam quality pulsed laser and energetic materials was studied. Fast and efficient ignition of pulsed fiber laser based on high beam quality is realized. Compared with semiconductor laser, the output brightness of fiber laser is high and the light energy is concentrated under the condition of the same output power, which is conducive to the instantaneous generation of high temperature hot spot when interacting with the agent, which can effectively improve the ignition efficiency. And the photoelectric conversion efficiency is high, can effectively reduce the energy supply. It is an ideal pyrotechnic device which can improve the safety of weapons and equipment in modern war.
