精密恒温角匹配KD P二倍频,三倍频系统

An angle phase matching KDP SHG and THG system with fine temperature control

本文报导了一种具有精密恒温的角相位匹配ＫＤＰ二倍频、三倍频系统，其特点是温度恒温控制在４０℃，稳定度０，１℃。在大功率输出的Ｎｄ：ＹＡＧ激光器中，实现０．５３μｍ和０．３５５μｍ波长的连续稳定运转，其光脉冲能量涨落＜±２％。

An angle phase matching KD P SHG and THG system with fine tem-perature control has been developed, the operating temperature is 40℃ and temperature stability is 0.1℃。 When the system applied in a high power output Nd:YAG laser,it can continuously and stable operate at 0. 5 3μm and 0.355μm。 The pulse energy fluctuation is less than ±0.2%。
