Abstract
In this paper, laser frequency-double and passive Q-switching are studied. The optimum coupling at end-pump and optimum design of resonator are also investigated. The maximum output power of TEM00 is 1.68 W at 1.06-μm wavelength. Optic-optic conversion efficiency is 48.6%, and the slope efficiency is 56.3%. The maximum output of green light is 0.235 W. The smallest pulse-width of green light is 27.42 ns, optic-optic conversion efficiency of green light is 7%, and beam quality factor M2<1.2. Thermal lens effect is discussed.
