掺Pr^(3+)固体激光器研究进展概述

Overview of research and development of Pr^(3+) doped solid-state lasers

可见光激光器在激光彩色显示、激光医疗、量子信息、光通讯等领域有着十分重要的作用。三价镨离子(Pr^(3+))因在可见光波段存在丰富的激光能级跃迁而备受人们关注。特别是近年来,激光二极管(LD)、光泵浦半导体激光器(OPSL)等商业化泵浦源的出现,更是使得掺Pr^(3+)固体激光器的研究得到了长足的发展。本文按照掺Pr^(3+)固体激光器连续、脉冲和单纵模三种输出类型,介绍了每种输出类型在特定波段处的典型工作,以时间为主线对掺Pr^(3+)固体激光器的研究历程与现状进行了概述,以及对未来掺Pr^(3+)固体激光器的研究做了展望。

Visible lasers are used extensively in laser color display,laser medical treatment,quantum information,optical communication,and other applications.Trivalent Pr-ion(Pr^(3+))has attracted much attention because of its rich transitions in the visible band.Especially in recent years,the emergence of commercial pump sources such as laser diode(LD)and optically pumped semiconductor laser(OPSL)has made great progress in the research of Pr^(3+)doped solid-state lasers.According to the three output types of Pr^(3+)doped solid-state lasers:continuous-wave output,pulse output and single longitudinal mode output,this paper introduces the typical work of each output type in a specific band.The research history and current status of Pr^(3+)doped solid-state lasers are summarized with time as the main line,and the future prospects of Pr^(3+)doped solid-state lasers are projected.
