摘要：
We report on electro-optic (EO) Q-switched intracavity second-harmonic generation (SHG) based on double-crystal RbTiOPO4 (RTP) in an 880 nm diode-end-pumped Nd:YVO4 laser for the first time. The double-crystal RTP performed simultaneously as a high repetition rate laser Q switch and a second-harmonic generator. At a repetition rate of 200 kHz, a maximum average output power of 2.51 W at 532 nm wavelength (M-x(2) = 1.243, M-y(2) = 1.131) and a shortest pulse width of 15.7 ns were achieved under an absorbed pump power of 21 W, corresponding to an optical-optical conversion efficiency of 11.9% and a slope efficiency of 12.8%, respectively.
