我们展示了一个紧凑的高功率单频Tm：YAG陶瓷激光器工作在1999.7 nm。通过在短腔长激光器中加入反射体布拉格光栅（VBG）实现了单频工作。激光发射的光谱线宽为1.10 MHz，最大输出功率为1.4 W，这受到激光器的泵浦诱导热透镜效应的限制。
We demonstrated a compact high-power single-frequency Tm:YAG ceramic laser operating at 1999.7 nm. Single-frequency operation was achieved by incorporating a reflection volume Bragg grating (VBG) in a laser with a short cavity length. The laser emission has a spectral linewidth of ∼10 MHz and a maximum output power of 1.4 W, which is limited by the pump-induced thermal-lens effect of the laser.
