报道了在重复频率调ＱＮｄＹＡＧ激光腔内，实现内腔光参量振荡器（ＩＯＰＯ）和光参量放大器（ＩＯＰＡ）的稳定运转，ＩＯＰＯ参量振荡阈值小于２０ｍＪ，获得最大输出能量为３５．９ｍＪ，相应的转换效率为４５％，中心输出波长为１．５７μｍ。该装置结构紧凑，易于小型化、全固化。
The stable operation of IOPO and IOPA is reported in QNdYAG laser with repetitive frequency modulation. The oscillation threshold of IOPO is less than 20mJ and the maximum output power is 35.9mJ. The corresponding conversion The efficiency is 45%, the center output wavelength is 1.57μm. The device is compact, easy to miniaturize, all-solidified.
