摘要
3~5μm波段中红外激光在遥感、通讯、气体检测、医疗等领域有着广泛的应用前景。直接激射固体激光器具有原理简单、结构轻巧等优势,是3~5μm波段中红外激光产生的重要手段。目前,这类激光器按照增益介质分类可划分为基于Er^(3+)、Ho^(3+)、Dy^(3+)、Pr^(3+)等稀土离子掺杂的固体激光器以及以Fe∶ZnSe为代表的过渡金属离子掺杂的固体激光器。本文分别介绍这两类直接激射固体激光器近些年来的研究进展,并对它们的技术路线以及发展前景进行总结。
The 3~5μm mid-infrared laser has a wide application prospect in remote sensing,communication,gas detection,medical treatment and other fields.Having the advantages of uncomplicated theory and simple structure,directly pumping solid-state lasers are important methods to emit 3~5μm mid-infrared laser.There are two kinds of directly pumping solid-state lasers,mainly distinguished by their gaining mediums,one is based on rare-earth ions(such as Er^(3+),Ho^(3+),Dy^(3+),Pr^(3+))doped solid-state lasers,and the other is transition-metal ions doped solid-state lasers.The recent progresses of directly pumping solid-state lasers are introduced and their technical principles and future developments are summarized in this paper.
