To address the low ignition efficiency and reliance on electricity in traditional solid-state pyrotechnic pumped lasers, we designed a system based on the principle of adiabatic compression, utilizing entirely non-electric compressed air to ignite the pyrotechnic materials in an Nd:YAG laser medium. This design improves ignition synchronicity and pyrotechnic material combustion efficiency, achieving a laser output threshold of 10 mg pyrotechnic agent and utilizing 30 mg KClO₄/Zr agent, resulting in a laser energy of 30.2 mJ with a pulse width of 10 ms. This advancement provides a new implementation pathway for small-scale non-electric high-energy lasers.
