摘要：

We report the performance of a periodically poled lithium niobate (PPLN) crystal inside a diode-pumped Nd:YVO4 laser for simultaneous laser Q switching and optical parametric oscillation. The monolithic PPLN crystal consists of two sections, a 1-cm-long 14-mu m-period electrode-coated section and a 4-cm-long 30-mu m-period section, functioning as a low-voltage Pockels cell and a quasi-phase-matched parametric gain medium, respectively. At a 150-V Q-switching voltage and a 6-kHz switching rate, we measured 25-mu J pulse energy and 4-kW peak power at 1.55 mu m with 9-W absorbed diode power. (c) 2005 Optical Society of America.
