我们描述了高功率运行的透明Tm：YAG陶瓷激光器的端面泵浦的80 W的激光二极管条在782 nm。研究了高功率Tm：YAG陶瓷激光器中Tm ~（3+）离子掺杂浓度和激光器结构的优化。在6at.%的泵浦功率下，获得了24.6W的连续波输出，斜率效率为38.2% Tm：YAG陶瓷板条激光器。据我们所知，这是迄今为止所报道的二极管条端面泵浦Tm：YAG陶瓷激光器的最高平均输出功率。
We describe the high power operation of transparent Tm:YAG ceramic lasers end-pumped by a 80 W laser-diode bar at 782 nm. The optimization of the Tm3+-ion doping concentration and the laser configuration for high power Tm:YAG ceramic lasers are investigated. We obtain the continuous wave (CW) output power of 24.6 W with the slope efficiency of 38.2% from a 6 at.% Tm:YAG ceramic slab laser. This is, to the best of our knowledge, the highest output average-power of diode-bar end-pumped Tm:YAG ceramic lasers ever reported.
