A compact passively Q-switched YVO4/Nd:YVO4/KTA intracavity optical parametric oscillator (OPO) is realized. With an end-pumping diode power of 16.6 W, output signal power of 932 mW and idler power of 415 mW are obtained at a pulse repetition rate of 101 kHz. The pulse widths and the beam quality factors are also analyzed for both signal and idler lasers.
Computational and experimental studies of the lasing characteristics of IR optical parametric oscillator (OPO) on the nonlinear crystal LiNbO3 were performed. Implemented outside the cavity ring scheme OPO with replaceable output mirrors allows the conversion of the pump frequency in parametric generation to 30 % over the tuning range from 1.41 to 4.24 microns
