| Abstract: | We demonstrated continuous-wave (CW) and Q-switched operation of a room-temperature Ho:YAP ring laser that is resonantly end-pumped by a diode-pumped Tm:YLF laser at 1.91 ??m. Continuous wave output power of 3 W at 2119 nm is obtained under the absorbed pump power of 10.17 W, corresponding to a slope efficiency of 60%. For the Q-switched regime the maximum pulse energy of 1.58 mJ and the minimum pulse width of 590 ns at the repetition rate of 1 kHz are achieved. |
