本文报道了一种新型室温中红外Ce3+掺杂Ge20Sb10Ga5Se65玻璃激光器的广泛研究。研究了输出耦合器传输对激光效率和发射光谱的影响。在4.1µm的脉冲Fe:ZnSe激光器泵浦下，5.2µm的最大输出能量为35 mJ，激光阈值约为60 mJ，斜率效率为21%。本文首次报道了中红外Ce：玻璃激光器的调谐范围：采用腔内棱镜，激光可在4.5 ~ 5.6µm光谱范围内连续调谐。内部损耗确定为每次往返低于9%。
An extensive study of a novel room-temperature mid-infrared Ce3+-doped Ge20Sb10Ga5Se65 glass laser is reported. An influence of output-coupler transmission on laser efficiency and emission spectra is investigated. Pumped by a pulsed Fe:ZnSe laser at 4.1 µm, a maximum output energy of 35 mJ is demonstrated at 5.2 µm, with a laser threshold of about 60 mJ and a slope efficiency of 21%. The tuning range of a mid-infrared Ce:glass laser is reported for the first time: with an intracavity prism, the laser is continuously tunable in the spectral range of 4.5-5.6 µm. The internal losses are determined to be below 9% per roundtrip.
