摘　　要：光学参量振荡器(OPO)是利用非线性晶体的混频特性实现频率变换器件,是获得可调谐相干光的有效途径之一。准相位匹配(QPM)OPO产生的红外波段光在红外军事对抗、大气环境监测、医学、特殊环境远距离监控以及光谱学研究等诸多领域有重要的应用价值。而连续(CW)周期性极化铌酸锂(PPLN)OPO是3—5μm中红外大功率连续激光源的最佳选择。本文阐述了QPM技术的原理和特点,综述了中红外CWOPO的发展状况,重点放在CWPPLNOPO技术的发展上,并指出了其发展趋势及应用前景。Optical parametric ascillators（OPO} can realize frequency transformation with its mixing frequency properly of nonlinear crystal, which is one of available effective approach to obtain tuned coherent light, Infrared light generated by QPM OPO has significant application in infrared military atmospheric environment detection, medicine, spectroscopy, laser radar and remote sensing, Moreover CW PPLN OPO is the best choice for high power mid - infrared CW laser sources in the range of 3 - 5μm. In the paper, principles and characteristic of QPM are introduced and discussed, important recent advances of CW OPO are synmaarized , with emphasis on CW PPLN OPO and its application prospect.
