摘　　要：介绍了在2μm波段陶瓷激光器的实验研究进展，主要包括高功率、高效率的Tm：YAG陶瓷激光器，半导体直接泵浦的Ho：YAG陶瓷激光器和Tm光纤激光泵浦的Cr^2＋：ZnSe烧结成型的陶瓷激光器，这些激光器的输出涵盖了2-2．4μm波段。由于2μm波段的激光陶瓷具有较长的上能级寿命和相对较低的声子能量，不仅在连续波输出时，而且在脉冲输出时具有潜在的高转换效率。还讨论了2μm波段陶瓷的光谱特性，以及这些特性对于2μm波段激光输出性能的影响。Recent progresses in 2μm wavelength ceramic lasers of laboratory have been introduced. The works include experimental research on the high power, high efficiency Tm：YAG ceramic lasers, directly pumped Ho：YAG ceramic lasers, and Tm-fiber lasers pumped Cr^2＋：ZnSe sintered ceramics lasers, which cover the wavelength range of 2-2.4μm. Because the 2 μm wavelength laser ceramics have longer lifetime of upper level and lower phonon energy, the laser presents potential high efficiency not only for the CW output, but also for the pulsed output. Furthermore, the spectrum characteristics of 2 μm ceramic and the influence to the laser performance have been discussed.
