Abstract
We report a continuous wave Tm:YAP laser resonantly pumped Ho:YAP laser in CW mode and passive Q-switched mode. Multilayer Cr:ZnS is used as the saturable absorber for the Q-switched operation. The maximum continuous wave output power of 6.36W at 2118.67nm was obtained, corresponding to a slope efficiency of 25.2% and the overall optical-to-optical conversion efficiency of 19.8%. The maximum pulse repetition frequency reached 41.25kHz and the minimum pulse width of 382ns was obtained at average output power of 5.24W. Meanwhile, the output beam spatial profile was close to fundamental TEM00 mode and the beam quality factor M2 was 1.4.
