摘　　要：概述了中红外激光器的应用背景,介绍了国外研究现状及发展趋势,提出了用固体办法实现中红外激光有效输出的技术途径和方案,对固体中红外激光输出所需要的2 μm激光泵浦源技术进行了探讨和方案比较,最终选用了 OPO 技术间接获得2 μm激光的方案。以二极管泵浦1.06 μm激光为泵浦源,采用双谐振腔内 KTP OPO 的方式,进行了激光实验,实现了功率23.9 W 的2 μm波长激光输出。在此2 μm激光泵浦源基础上,提出了实现室温运转的中红外固体激光 ZnGeP_2 OPO 的技术方案并进行了实验,最终成功实现中红外激光输出,在约5 kHz 时,中红外激光输出功率4.09 W。In this paper,the solid measure to implement mid-infrared laser output availably is provided.The indirect OPO scheme to obtain 2μm laser is adopted finally by two scheme comparison.2 μm laser experiment is performed adopting double-resonance intro-cavity KTP OPO pumped by LD pumped 1.06 μm laser,and 23.9 W of 2 μm laser output is implemented,on the basis of 2 μm laser pump source,the ZnGeP_2 OPO technique scheme of mid-infrared solid state laser in room operation is offered,mid-infrared laser experiment is performed.Finally,the output of mid-infrared laser is implemented,the result of 5 kHz,4.09 W output of mid-infrared laser is obtained.
