摘　　要：为了解决传统固体烟火泵浦激光器点火效率低和电能依赖的问题,根据绝热压缩原理,设计使用了完全无电的压缩空气点燃烟火药泵浦Nd:YAG激光介质,提高了点火同步性和烟火药燃烧效率,实现了激光输出阈值药剂量10 mg,使用30 mg KClO4/Zr药剂,获得了30.2 mJ的激光能量,脉冲宽度10 ms,为小型无电高能激光器提供了一条新的实现路径。To address the low ignition efficiency and reliance on electricity in traditional solid-state pyrotechnicpumped lasers,we designed a system based on the principle of adiabatic compression,utilizing entirely non-electriccompressed air to ignite the pyrotechnic materials in an Nd:YAG laser medium.This design improves ignitionsynchronicity and pyrotechnic material combustion efficiency,achieving a laser output threshold of 10 mg pyrotechnicagent and utilizing 30 mg KClO4/Zr agent,resulting in a laser energy of 30.2 mJ with a pulse width of 10 ms.Thisadvancement provides a new implementation pathway for small-scale non-electric high-energy lasers.
