摘　　要：人眼安全1550 nm波段激光位于良好的大气传输窗口,以及室温工作的Ge和InGaAs探测器的探测灵敏区,可被广泛应用于激光雷达、激光测距和遥感测量等领域。利用激光二极管泵浦Er^3+掺杂晶体是一种直接输出1550 nm波段紧凑型全固态激光的有效方法。本文主要综述了近年来采用Er^3+掺杂晶体作为增益介质的1550 nm波段全固态激光的研究进展,并对该波段激光的进一步发展进行了展望。Eye-safe 1550-nm laser is located in an excellent atmospheric transmission window and detection-sensitive region of Ge and InGaAs photodiodes operating at room temperature.Therefore,such laser can be widely used in many fields,including lidar,laser ranging,and remote sensing.Diode-pumped Er^3+-doped crystals are considered as an effective method for directly obtaining the compact 1550-nm all-solid-state laser.In this paper,recent research progress in 1550-nm all-solid-state lasers based on Er^3+-doped crystals is reviewed.Moreover,further development of 1550-nm all-solid-state lasers is discussed.
