✦ Synopsis

We report the room temperature continuous wave and acousto-optically Q-switched Ho:YAG laser double-pass pumped by a diode-pumped Tm:YLF laser. Continuous wave output power of 10.5 W at 2090 nm is obtained under the incident pump power of 18.1 W, corresponding to a conversion efficiency of 58.0% and a slope efficiency of 65.7%. For the Q-switched regime the maximum pulse energy of 1.0 mJ and the minimum pulse width of 25 ns at the repetition rate of 10 kHz are achieved, resulting in a peak power of 40.0 kW.
