摘　　要：中波2.79μm波段的激光在生物医学、非线性光学以及军事等领域有着广泛的实用前景和发展空间。目前用于获得中波2.79μm波段激光的增益介质主要为Er:YSGG或Er,Cr:YSGG等激光晶体,由于基质YSGG热导率低,致使激光器在运行时产生的热效应比较严重,因此,开展其泵浦技术研究有重要的实际意义。针对Er,Cr:YSGG晶体的泵浦技术开展了详细的分析和讨论,并结合近年来新出现的泵浦模式,对下一步的技术发展进行了分析和展望。Lasers in the mid-wave 2.79μm band have a wide range of practical prospects and development in the fields of biomedicine,nonlinear optics,and the military.At present,the gain medium used to obtain medium-wave 2.79μm band laser is mainly Er:YSGG or Er,Cr:YSGG laser crystals,due to the low thermal conductivity of the substrate YSGG,resulting in the laser operating with serious thermal effects,so it is of great practical importance to carry out research on its pumping technology.This paper carries out a detailed analysis and discussion of the pumping technology for Er,Cr:YSGG crystals,and analyzes and foresees the next technological development in light of the newly emerged pumping modes in recent years.
