报道了单脉冲能量大于10μJ的腔倒空锁模皮秒激光器。通过实验完成了光纤耦合激光二极管端面抽运Nd:YVO4晶体、半导体可饱和吸收镜(SESAM)锁模的大功率皮秒激光振荡器后,在锁模腔内插入BBO电光晶体,实现重复频率1Hz～10kHz连续可调的电光腔倒空锁模运转。在抽运功率17.9 W时,获得了单脉冲能量12.5μJ、重复频率10kHz、脉冲宽度24.7ps的激光输出。
A cavity-pumped mode-locked picosecond laser with a single pulse energy of more than 10 μJ was reported. After experimenting, the high power picosecond laser oscillator with Nd: YVO4 end-pumped by fiber-coupled laser diode and the SESAM mode-locked laser oscillator is completed. The BBO electro-optic crystal is inserted into the cavity and the repetition rate is 1Hz ~ 10kHz continuously adjustable electro-optical cavity lock-up mode. At a pumping power of 17.9 W, a laser output of 12.5 μJ single pulse energy, 10 kHz repetition rate and 24.7 ps pulse width was obtained.
