An actively -switched mid-infrared Fe:ZnSe laser pumped by a continuous wave fluoride fiber laser has been developed. Stable operation with a pulse duration of 20 ns and a repetition rate of 40 kHz at 4 µm was achieved. The maximum peak power was 1.1 kW. The high-repetition rate, high-peak power nanosecond pulsed laser, which has been created for the first time, to the best of our knowledge, in an actively -switched Fe:ZnSe laser, should prove a suitable light source for laser processing and molecular sensing.
一种由连续波氟化物光纤激光器泵浦的主动开关中红外铁掺杂硒化锌（Fe:ZnSe）激光器已被研制出来。在4μm波长下实现了脉冲持续时间为20ns、重复频率为40kHz的稳定运行。最大峰值功率为1.1kW。据我们所知，首次在主动开关Fe:ZnSe激光器中产生的高重复频率、高峰值功率纳秒脉冲激光器，应能证明是一种适用于激光加工和分子传感的光源。
