摘　　要：可见光激光在数据存储、光通讯、激光显示、激光医疗、激光打印以及科学研究等领域具有非常重要的应用价值。随着蓝光LD泵浦源的商用化,直接泵浦稀土离子掺杂激光晶体实现可见光激光输出吸引了人们极大的研究兴趣。目前,可见光稀土离子主要集中在Pr^3+、Dy^3+、Tb^3+和Sm^3+等。其中,Pr^3+的研究较多,发光波长涵盖面较广,发射波段覆盖蓝光、绿光、红光、橙光;Dy^3+和Tb^3+因为能够发射黄光以填补Pr^3+的不足也吸引了广泛的研究;此外,Sm^3+和Eu^3+也是典型的可见波段稀土发光离子。本文综述了近几年可见波段稀土离子掺杂激光晶体的研究现状,主要以Pr^3+、Dy^3+、Tb^3+和Sm^3+掺杂YAlO3(YAP)、Mg:SrAl12O19(SRA)等晶体为研究对象,总结了一套适合Pr^3+掺杂材料的判据,对晶体生长、结构、热学性能、偏振光谱性能和激光性能进行了系统的研究。Visible laser has been widely used in data storage, optical communication, laser display, laser medical treatment, laser printing, and scientific research. With the development of commercial blue light LD, the direct pumping of rare-earth ions doped laser crystals have attracted a lot of interests. Currently, visible ions mainly concentrat on Pr^3+, Dy^3+, Tb^3+, and Sm^3+. Trivalent praseodymium (Pr^3+) is a famous rare-earth ion with extensive laser transitions in visible region such as blue, green, red and orange light. However, there is still a region in yellow emission which is not covered by Pr^3+. Dy^3+ and Tb^3+ have attracted much attention because of their yellow laser transitions. In addition, Sm^3+ and Eu^3+ are also typical visible rare-earth ions. In this paper, we mainly reviewed properties of rare-earth ions doped laser crystals for visible lasers, especially Pr^3+, Dy^3+, Tb^3+ and Sm^3+-doped YAlO3 (YAP), SrAl12O19 (SRA) crystals. A design criterion for Pr^3+ doped oxide materials was summarized. The crystal growth, structure, thermal properties, polarization spectroscopic and laser characteristics were analyzed in detail.
