A passively switched Ho(3+), Pr(3+) codoped fluoride fiber laser using a semiconductor saturable absorber mirror (SESAM) is demonstrated. Q-switching and partial mode-locking were observed with the output power produced at a slope efficiency of 24% with respect to the absorbed pump power. The partially mode-locked 2.87 μm pulses operated at a repetition rate of 27.1 MHz with an average power of 132 mW, pulse energy of 4.9 nJ, and pulse width of 24 ps.
我们展示了一种使用半导体可饱和吸收镜（SESAM）的被动切换 Ho(3+)、Pr(3+)共掺氟化物光纤激光器。我们观察到了 Q 开关和部分锁模现象，其输出功率相对于吸收的泵浦功率具有 24%的斜率效率。部分锁模的 2.87μm 脉冲在重复频率为 27.1MHz 时工作，平均功率为 132mW，脉冲能量为 4.9nJ，脉冲宽度为 24ps。
