| 摘 要： | An efficient high-energy eye-safe optical parametric oscillator （OPO） based on a type-Ⅱ non-critically phasematched KTP crystal is demonstrated. The KTP OPO is pumped by a quasi-cw diode side-pumped electrooptic Q-switched Nd：YAG laser in a compound-cavity configuration. The maximum output energy of the signal wavelength at 1.57 μm b 66.5 m J, corresponding to an electrical-to-optical conversion efficiency of 4.47% and an optical-to-optical conversion efficiency of 12.1%. The pulse width （FWHM） is about 3.6 ns with a peak power of 18.5 MW. The output energy is insensitive to repetition rate and demonstrates good stability.
