| Abstract: | We report the continuous wave and acousto-optically Q-switched operation of an in-band dual-end-pumped Ho:YAP laser at room temperature. A continuous wave output power of 11.0W at 2118 nm was obtained at an absorbed pump power of 19.8 W, corresponding to a slope efficiency of 62.1%. For the Q-switched mode, a maximum pulse energy of about 1.07 mJ and a minimum pulse width of 29 ns at a repetition rate of 10 kHz were achieved, resulting in a peak power of 36.9 kW. |
