摘要
利用ＮｄＹＡＧ激光增益介质的法拉第效应，以及光束在非平面环形谐振腔中传播产生的偏振面旋转，使激光二极管泵浦的环形ＮｄＹＡＧ激光器单向运转，获得单频激光输出。最大单纵模激光（１．０６４μｍ）输出为３６５ｍＷ，功率波动小于２％，短期频率漂移小于４５ＭＨｚ。并利用内腔倍频技术得到单频绿光输出，最大单纵模绿光（５３２ｎｍ）输出为７５ｍＷ，功率波动小于４％。
By using the Faraday effect in Nd∶YAG and the rotation of polarization in a non plannar ring resonator, single frequency output from an all solid state out of plane Nd∶YAG ring laser is demonstrated. The maximum single frequency output of 365 mW at 1064 nm has been achieved with slope efficiency of 36.2%, the intensity fluctuation is less than 2% and the frequency shift is less than 45 MHz in 1 minute. Single frequency output of 75 mW at 532 nm has been obtained by intracavity frequency doubling. The intensity fluctuation for 532 nm is less than 4%.
