A maximum single-longitudinal-mode and fundamental transverse mode output power of 478 m W at the wavelength of 2091.06 nm is achieved with a pump power of 16.3 W, corresponding to an optical-to-optical efficiency of 2.9% and a slope efficiency of 7.9%. The single-longitudinal-mode and fundamental transverse mode are less sensitive to the rotating of the corner cube. The results indicate the potential impact of a single-longitudinal-mode Ho： YA G laser with corner cube geometry to improve the anti-maladjustment stability.展开更多
