摘要：

We demonstrate a compact and efficient Ho:YLF slab laser that is pumped by a self-made Tm:YAP slab laser. The maximum output power of 125 W at 2064 nm was obtained with the incident pump power of 245 W. To the best of our knowledge, this is the first report for an Ho:YLF laser oscillator to reach hundred-watts-level output power. The slope efficiency with respect to the incident pump power was 62.5%, and the optical-to-optical conversion efficiency was 51%. The RMS instability of the maximum output power was measured to be 0.24% in 30 min. The beam quality Factors M-2 were 475 and 1.59 in the x and y directions, respectively.
