摘要:
中红外全固态光学参量振荡器，由于宽的调谐范围、低阈值、高效率、高重复率及小型化的优点，在光电对抗、激光雷达、激光测距、光谱测量以及在环境监测等领域都有广泛的应用前景。全固态中红外激光器一直是激光技术研究的热点。本文重点介绍了基于双折射相位匹配晶体（如KTA、KTP）和准相位匹配晶体（如PPKTP、PPKTA、PPLN）的中红外内腔单谐振（ISRO）光学参量振荡器的一些最新的研究进展，并对其发展趋势进行了展望。
Abstract:
Mid-infrared all-solid-state optical parametric oscillator, due to wide tuning range, low threshold, high efficiency, high repetition rate and the advantages of miniaturization, have widespread optoelectronic countermeasures, laser radar, laser ranging, spectral measurements and the areas of environmental monitoring. In recent years there has been increasing interest in the mid-infrared OPO. This article focuses on research and progress of middle-infrared single resonant OPO（ISRO）, which is based on birefringent phase-matching crystals (such as KTA, KTP) and quasi-phase matching crystals (such as PPKTP, PPKTA, PPLN). We also discuses the development trend of ISRO.
