Abstract—We demonstrated continuous-wave (CW) and Q-switched operation of a Tm,Ho:YAP ring laser at
77 K. The maximum CW output power of 2 W at 2130.7 nm was obtained under the incident pump power of
12 W, corresponding to a slope efficiency of 23% and an optical-to-optical efficiency of 16.7%. For the
Q
switched regime the maximum output energy of 5 mJ with the pulse width of 160 ns at the repetition rate of
100 Hz was achieved, corresponding to a peak power of 31.25 kW.
