报道了二极管端面泵浦的Tm：YLF激光器在1.91微米附近产生的高功率(>；36W)，光束传输因子M-2类似于2。利用Tm：YLF激光器获得的1.91微米的发射和高亮度，我们用Ho：YLF共振端面泵浦I-5(7)腔，获得了类似于19W的连续波输出。获得的二极管-Ho光-光转换效率接近18%。利用连续泵浦和重复调Q结构，Tm：YLF泵浦的Ho：YLF激光器在15 kHz时获得了16W的输出功率和接近1.48的M-2，调Q频率范围也达到了9~50 kHz。
We report high power (>36 W) with beam propagation factor M-2 similar to 2 in a diode end-pumped Tm:YLF laser generating output near the 1.91-mum region. Using the 1.91-mum emission and high brightness achieved with the Tm: YLF laser we resonantly end-pump the Holmium I-5(7) manifold in Ho:YAG and demonstrate similar to 19 W of continuous-wave (CW) output. The diode-to-Holmium optical-to-optical conversion efficiency achieved is similar to 18%. Using a CW pumped and repetitively Q-switched configuration, the Tm:YLF pumped Ho:YAG laser achieves >16 W of output power with an M-2 similar to 1.48 at 15 kHz, A Q-switched frequency range of 9 to >50 kHz is also achieved.
