摘要：

A method of generating 1.57 mu m pulse-series eye-safe laser based on optical parametric oscillator (OPO) was developed. The 1.57 mu m pulse-series OPO was pumped by a Q-switched Nd:YAG laser with a variable reflectivity unstable resonator. Every pulse-series includes three micro-pulses, and the pulse repetition rates, pulse numbers and pulse intervals were adjustable. The maximum output energy of the 3-micro-pulse-series was 274 mJ. The optical-optical efficiency of the OPO was about 40%.
