A diode-pumped, actively Q-switched 2.8 μm fiber laser oscillator with an average output power of more than 12 W has been realized through the use of a 35 μm core erbium-doped ZBLAN fiber and an acousto-optic modulator; to our knowledge, this is the first 3 μm pulsed fiber laser in the 10 W class. Pulse energy up to 100 μJ and pulse duration down to 90 ns, corresponding to a peak power of 0.9 kW, were achieved at a repetition rate of 120 kHz.
已实现了平均输出功率超过 12 W 的二极管泵浦、主动调 Q 的 2.8 μm 光纤激光振荡器，其采用了 35 μm 芯掺铒 ZBLAN 光纤和声光调制器；据我们所知，这是首台 10 W 级的 3 μm 脉冲光纤激光器。在重复率为 120 kHz 的情况下，获得了 100 μJ 的最大脉冲能量和 90 ns 的最短脉冲持续时间，对应的峰值功率为 0.9 kW。
