报道了一种宽调谐、窄线宽的Tm：YAG陶瓷激光器。腔内采用体布拉格光栅作为波长选择的折叠镜。波长调谐范围为1956.2~1995年，总调谐范围为38.7nm.在整个调谐范围内，线宽约为0.1 nm。在吸收泵浦功率为37.8W时，获得了最大输出功率为1.51W的1990.5 nm激光。在不同波长下观察到不同的饱和行为。
We report on a widely tunable, narrow linewidth operation of a Tm:YAG ceramic laser. A volume Bragg grating is used in the cavity as a folding mirror for wavelength selection. The wavelength is tuned from 1956.2 to 1995 nm, leading to a total tuning range of 38.7 nm. The linewidth is around 0.1 nm over the whole tuning range. A maximum output power of 1.51 W at 1990.5 nm is achieved at 37.8 W absorbed pump power. Different saturation behaviors are observed in the laser performances at different wavelengths.
