Abstract
A high power single crystal Ho:YAG laser was reported in this paper. With dual-end pump structure, maximum continuous wave power of 108W was achieved with slope efficiency of 63.2% and optical efficiency of 57.9%. With an acousto-optic Q-switch, maximum average output power of 106W at the pulse repetition frequency of 20kHz was achieved with pulse energy of 5.3mJ and pulse width of 21ns, corresponding to a peak power of approximately 252kW. The output wavelength was 2090.7nm with FWHM linewidth of 0.4nm. The beam quality factor of M2 was estimated to 1.6.
