【摘要】 采用四镜环行谐振腔，通过正确选择Ｎｄ：ＹＡＰ棒的方位，提高了内腔激光偏振度，降低了热效应的影响，在输入１．２ｋＷ电功率的情况下，输出单频激光功率为１．２Ｗ．波动小于２％．频率的长期稳定性小于±０．４ＭＨｚ。更多还原

【Abstract】 By using a 4-mirror ring cavity and choosing the appropriate direction of the Nd:YAP rod,the laser polarizability and the influence of the thermal effect on laser insidethe cavity have been improved.The single frequency output up to 1.2 W has been obtainedwith the input POwer of 1.2 kW,the fluctuation is less than 2%,and the long termfrequency stability is better than ±0.4 MHz.更多还原
