摘要
报道了单脉冲能量大于10 μJ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1 Hz~10 kHz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12.5 μJ、重复频率10 kHz、脉冲宽度24.7 ps的激光输出。
Abstract
This paper reports the cavity-dumped mode-locked picosecond laser with single pulse energy greater than 10 μJ for the first time in China, to the best of our knowledge. We complete semiconductor saturable absorption mirror (SESAM) mode-locked high-power picosecond laser oscillator with a fiber-coupled laser diode end-pumped Nd:YVO4 crystal. Then we insert BBO electro-optic crystal to the clamping cavity, realizing the repetition frequency 1 Hz~10 kHz continuously adjustable electro-optical cavity-dumped mode-locked operation. When the pump power is 17.9 W, pulses with single pulse energy of 12.5 μJ and repetition frequency of 10 kHz are obtained, whose pulse width is about 24.7 ps.
