We demonstrated >80 W picosecond output at a pulse repetition frequency of 100 MHz from a dual Nd:YVO(4) amplifier laser system consisting of a phase-conjugate Nd:YVO(4) bounce amplifier combined with a second diode-side-pumped Nd:YVO(4) bounce amplifier. The output exhibited high quality spatial form with M(2) < 1.8 and a pulse duration (FWHM) of 9.2 ps. A peak power of >7.4 MW with an average power of 78.5 W was also achieved at a pulse repetition frequency of 1.0 MHz.
我们展示了一个由相位共轭Nd:YVO₄ 反射放大器与第二个二极管侧面泵浦Nd:YVO₄ 反射放大器组成的双Nd:YVO₄ 放大器激光系统，在100 MHz的脉冲重复频率下输出功率超过80 W的皮秒脉冲。输出呈现出高质量的空间形态，M² < 1.8，脉冲持续时间（半高宽）为9.2 ps。在1.0 MHz的脉冲重复频率下，还实现了峰值功率超过7.4 MW、平均功率为78.5 W的输出。
