摘　　要：基于非线性频率变换技术的中红外固体激光器,受限于光学晶体的损伤阈值、镀膜工艺和逆转换效应,输出功率相对较低,而光参量放大技术可以有效改善这个问题。介绍了光参量放大技术的典型结构、特点以及常用光学晶体,评述了光参量放大技术提高纳秒量级中红外固体激光器输出功率的研究进展,分析了光参量放大技术在提高纳秒量级中红外固体激光器输出功率方面面临的挑战。The output power of the mid-infrared solid-state laser based on nonlinear frequency conversion technology,which is limited by the back conversion effect,is relatively low due to the damage threshold and coating process of the optical crystal,and the optical parametric amplification technology can effectively solve this problem.In the paper,the typical structure and characteristics of optical parametric amplification technology and common optical crystals are introduced.The latest development of optical parametric amplification technology to increase the output power of nanosecond mid-infrared solid-state laser is reviewed.Scientific challenges of optical parametric amplification technology in increasing nanosecond mid-infrared solid-state laser output power are also analyzed.
