CHEL3300激光器首次尝试采用1套磁脉冲压缩快关控制的L-C反转电路实现3个独立的激光腔放电。通过调整磁脉冲压缩开关到各个放电腔电路的电感确保3个放电腔按照“天光一号”系统1次分束的要求以20ns的时间间隔依次放电。实验证明,CHEL3300激光器作为“天光一号”系统的ASE种子光 CHEL3300 lasers for the first time try to use a magnetic pulse compression fast switching control L-C inverter circuit to achieve three independent laser cavity discharge. By adjusting the inductance of the magnetic pulse compression switch to each discharge cavity circuit, three discharge cavities are sequentially discharged at intervals of 20 ns according to the requirements of the first beam splitting of the “Sky One” system. Experiments show that, CHEL3300 laser as “Sky One” ASE seed light system
