Abstract

Abstract A high-energy, alignment-insensitive, injection-seeded Q-switched Ho:yttrium aluminum garnet (YAG) single-frequency laser is developed. Both the slave Q-switched laser and the seed laser are Ho:YAG ring lasers based on a pair of corner cubic reflectors. The seed laser has an available power of 830 mW at 2096.667 nm. At 100 Hz, the Q-switched Ho:YAG laser provides a single-frequency pulsed output using injection-seeded technology. The 7.3 mJ single-frequency pulse energy from the slave laser has a pulse width of 161.2 ns and is scaled to 33.3 mJ after passing through the Ho:YAG single-pass amplifier. According to the measurement results of the heterodyne beating technique, the single-frequency pulse has a half-width of 4.12 MHz.

高能，对准不敏感，注入种子q开关Ho:钇铝石榴石单频激光器

研制了一种高能、对准不敏感、注入种子调q的钇铝石榴石(YAG)单频激光器。从调q激光器和种子激光器都是基于一对角立方反射器的Ho:YAG环形激光器。种子激光器在2096.667 nm处具有830 mW的可用功率。在100hz时，调q的Ho:YAG激光器使用注入种子技术提供单频脉冲输出。从端激光器产生的7.3 mJ单频脉冲能量，脉冲宽度为161.2 ns，经过Ho:YAG单通放大器后被缩放到33.3 mJ。根据外差跳动技术的测量结果，单频脉冲的半宽为4.12 MHz。
