Abstract
A diode-side-pumped high-power single-wavelength Nd:YAG continuous wave (cw) laser is described. Through reasonable coating design of the cavity mirrors, the strongest line as well as the one have been successfully suppressed. The laser output powers corresponding to four groups of different output couplers operating at single wavelength have been compared. The output coupler with the transmission has the highest output power, and a cw output power was achieved at the pumping power of . The optical–optical conversion efficiency is 23.6%, and the slope efficiency is 46%. The output power is higher than the total output power of the dual-wavelength laser operating at and in the experiment.
