Efficient room temperature mid-infrared laser action in a Ce-doped chalcogenide fiber was demonstrated. The fiber had a doped selenide glass core in an undoped sulfide glass cladding. The pump source was a CW Fe:ZnSe laser emitting at 4.14 µm. The optimized fiber length allowed obtaining up to 7 mW of 5.06 µm output with 17% slope efficiency at room temperature.
在掺铈硫族化物光纤中实现了高效的室温中红外激光作用。该光纤具有掺杂硒化物玻璃芯和未掺杂的硫化物玻璃包层。泵浦源是一台连续波Fe:ZnSe激光器，发射波长为4.14 µm。优化后的光纤长度使得在室温下能够获得高达7 mW的5.06 µm输出，斜率效率为17%。
