We propose and demonstrate an all-fiber self-Q-switched erbium laser system that is saturable-absorber Q switched by the mismatch of the mode-field areas in the resonator and stabilized with a saturable-amplifier pump switch. Sequential pulses with a pulse energy of 8-6 microJ and a pulse duration of 80-320 ns, corresponding to a pulse repetition rate of 0.25-1 kHz, were obtained using a cw 980 nm laser-diode pump. A peak pulse power of near 100 W was achieved.
我们提出并演示了一种全光纤自调 Q 铒激光器系统,该系统通过谐振腔中模式场面积的失配对可饱和吸收体进行调 Q ,并通过可饱和放大器泵浦开关进行稳定。使用连续 980nm 激光二极管泵浦,可获得脉冲能量为 8-6μJ、脉冲持续时间为 80-320ns、对应脉冲重复率为 0.25-1kHz 的脉冲序列。实现了近 100W 的峰值脉冲功率。
