本文研究的望远镜热不灵敏腔、大体积ＴＥＭ００模运转的高功率Ｎｄ：ＹＡＧ激光器。重复频率１～１０ｐｐｓ二级放大后每个脉冲的输出能量１．０６ｕｍ为１．１Ｊ，０．５３ｕｍ为５２０ｍＪ，Ｏ．３５５ｕｍ为１８０ｍＪ。脉冲能量起伏小于±２％。１．０６ｕｍ光束发散角小于１ｍｒａｄ。
The telescope thermal insensitive chamber studied in this paper is a high-power Nd: YAG laser with a large volume TEM00 mode operation. The repetition rate of 1 ~ 10pps after secondary amplification of each pulse output energy of 1.06um 1.1J, 0.53um to 520mJ, O. 355um is 180mJ. Pulse energy fluctuations less than ± 2%. 1.06um Beam divergence less than 1mrad.
