报道了低成本、非制冷法布里-玻罗腔半导体增益开光激光器稳定地产生超短脉冲的实验研究.通过使用外部连续光注入,增益开光激光器的脉冲抖动得到了有效的抑制.实验结果表,明当选择合适功率的连续光注入到非制冷半导体增益开关激光器腔内,可以稳定地产生脉宽26ps、抖动低于400fs、重复频率2.5GHz的脉冲序列. This paper reports the experimental research of low cost, uncooled Fabry-Perot-cavity semiconductor gain open-laser and stable generation of ultrashort pulse.The pulsed jitter of gain-on laser is effectively suppressed by using external continuous light injection. , When the continuous light of the right choice of power is injected into the uncooled semiconductor gain switching laser cavity, a pulse sequence with a pulse width of 26 ps, a jitter of less than 400 fs and a repetition frequency of 2.5 GHz can be stably generated.
