1.47～4μm光参量振荡器
An optical parametric oscillator (OPO) tunable in 1.47～4μm
摘要
采用电光调Q脉冲YAG激光器泵浦,温度调谐和腔内工作方式,在50°切割的LiNbO3晶体中,首次获得以3.3μm为中心调谐波长,调谐区为1.47～4μm的红外参量振荡。其输出能量大于100μJ/pulse,线宽约3cm~(-1),重复率达40pps,波长稳定性优于5cm~(-1)。
Abstract
IR intracavity optical parametric oscillation is obtained by using an electro-optic Q-switched Nd:YAG laser as the pumping source and a 50°-cut LiNbO3 crystal as the oscillator. The wavelength is tuned by varying the temperature of LiNbO3. The tunable range is 1.47～4μm with output energy over 100μJ per pulse and linewidth less than 5cm-1. This OPO has been applied in laser chemistry with good experimental results.
