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。
A series of Nd: YVO4-KTP intracavity frequency doubling lasers with an LD pumped by acousto-optic modulator Q were developed. The output of a series of TEM00 mode and a stable 532um green laser pulse with a frequency up to 100kHz was obtained. The threshold pump power was 27mW. At a pump power of 570mW, the peak power of the green laser pulse reaches 1100W and the pulse width is 4.6us. The output power is stable, and the output power variation is less than ± 2% under the operating temperature change of ± 5 ℃. Such devices are expected to be widely used.
