All solid state passively Q switched frequency doubled intra cavity Nd:GdVO4/KTP

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 i
