本文报道了一种基于有源脉冲二极管泵浦系统的增益开关Er:ZBLAN光纤激光器的工作原理和性能。所产生的激光脉冲提供高峰值功率，同时保持高平均功率和效率的连续波政权。测量到的脉冲持续时间约为300ns，几乎与泵浦重复频率无关。据我们所知，对于二极管泵浦Er:ZBLAN光纤激光器，获得的最大峰值功率为68w，是报道的最高峰值功率，并且在100 kHz重复频率下的平均功率为2w，比以前报道的脉冲状态下的平均功率高2个数量级。得到的坡度效率为34%。(C) 2011美国光学学会
We report on the operation and performance of a gain-switched Er:ZBLAN fiber laser based on an active pulsed diode pump system. The produced laser pulses offer high peak powers while retaining the high average powers and efficiency of the cw regime. The measured pulse duration was about 300 ns and nearly independent of the pump repetition frequency. The maximum obtained 68 W of peak power is the highest reported, to our knowledge, for diode-pumped Er:ZBLAN fiber lasers, and the 2 W of average power at the repetition frequency of 100 kHz is 2 orders of magnitude higher than previously reported average power in a pulsed regime. The obtained slope efficiency was 34%. (C) 2011 Optical Society of America
