A multiwavelength operation generated from an intracavity optical parametric oscillator (OPO) pumped by a passively Q-switched Nd:GGG laser with a Cr(4+):YAG saturable absorber is demonstrated. KTiOPO4 simultaneously worked as nonlinear OPO and Raman crystal. Maximum output powers of 302 mW at 1566.8 nm and 115 mW at 1124.9/1160.7 nm were obtained at a diode power of 10.5 W, corresponding to the optical-to-optical conversion efficiencies of 2.88% and 1.1%, respectively. The measured shortest… CONTINUE READING
