摘要
翠绿宝石晶体是一种性能优良的宽带可调谐激光增益介质,具有荧光寿命长、饱和能量密度高、吸收带宽较宽以及热机械性能优良等特点.除闪光灯外,翠绿宝石晶体还可以使用蓝光激光二极管、红光激光二极管、绿光激光器、黄光激光器等多种可见光光源进行泵浦.随着激光二极管技术的成熟及其商业化应用,利用红光激光二极管泵浦的翠绿宝石激光器逐渐成为固体激光领域的研究热点.本文首先介绍了翠绿宝石晶体的各种特性,并着重对基于闪光灯以及各类激光二极管泵浦的翠绿宝石激光器在国内外的发展进行综述,包括翠绿宝石连续激光、翠绿宝石调Q激光、翠绿宝石锁模激光、以及基于翠绿宝石的紫外激光.最后,阐述了翠绿宝石激光光源在医疗、雷达、显微等领域中的应用并对其未来发展提出了展望.
Alexandrite crystal is an excellent broadband tunable laser gain medium with long fluorescence lifetime,high saturation energy density,wide absorption bandwidth and excellent thermo-mechanical properties.In addition to the flash lamp pumping,a variety of visible light sources can also be used as the pumping source such as blue laser diodes,red laser diodes,green lasers,yellow lasers,etc.With the maturity and commercial application of laser diode technology,the alexandrite lasers pumped by red laser diodes have become a hot topic in the field of solid-state lasers.The characteristics of alexandrite crystal are firstly introduced.The domestic and international research progress of alexandrite lasers pumped by flash lamp,laser diodes,etc.are summarized,including continuous,Q-switched,mode-locked and ultraviolet lasers.Finally,the recent advances in their applications to dermatology,lidar,microscope,etc.are introducted and the future developments of alexandrite solid-state lasers are prospected.
