摘　　要：研制成用ＬＤ泵浦的声光调Ｑ的Ｎｄ：ＹＶＯ４－ＫＴＰ腔内倍频激光器，得到了ＴＥＭ００模、频率高达１００ｋＨｚ的稳定的５３２ｕｍ绿激光脉冲系列输出，阈值泵浦功率为２７ｍＷ；在连续５７０ｍＷ的泵浦功率下，绿激光脉冲的峰值功率达１１００Ｗ，脉宽为４．６ｕｓ；输出功率稳定，在±５℃的工作温度变化下，输出功率变化小于±２％。此种器件可望得到广泛的应用。The paper reported the first acoustooptic Q-switched Nd:YVO4-KTP intracavity frequency doubling laser in China.Series pulses of 532 um green laser in TEM00 mode with threshold pumping power of 27mW have been measured. Under CW pumping power of 570mW,the peak power of output beam exceeding 1100W with pulse width of 4.6 us is demomstrated.The fluctuation of output power is less than ±2% when the temperature change is smaller than±5℃.
