摘要：

Er³⁺掺杂的晶体能够产生2.7~3.0 μm波段中红外激光,在激光医疗、光通讯、环境探测和光电对抗等领域具有重要的应用。基于本课题组近年来开展的Er³⁺激活中红外激光晶体的相关工作,本文综述了共掺稀土离子对Er³⁺激活晶体光谱性能的影响:包括敏化离子Cr³⁺、Yb³⁺等的敏化作用增强了Er³⁺的特征吸收峰;退激活离子Pr³⁺、Ho³⁺等的退激活效应抑制了自终态瓶颈效应;以及共掺Nd³⁺所起的敏化和退激活双重作用,并对中红外激光的研究趋势和前景进行了展望。

Abstract:

The Er³⁺-doped crystals can produce 2.7~3.0 μm mid-infrared(MIR) lasers, which have attracted much attention for their numerous applications in laser medical surgery, optical communication, enviromental detector and electro-optical countermeasure, etc. Based on the past few years' work on the study of Er³⁺ activated crystals by our team, we review the effect of co-dopant rare-earth ions on the spectroscopic properties of Er³⁺ activated MIR laser crystals, including the sensitizing ions Cr³⁺, Yb³⁺, etc. which can enhance the intensity of characteristic absorption peaks of Er³⁺; the deactivating ions Ho³⁺, Pr³⁺, etc. which can inhibit the self-termination bottleneck effects, furthermore, the co-dopant Nd³⁺ion can play a dual role at the same time. In the end, the expectations on the study of MIR lasers are presented.

Key words: Er ion, mid-infrared laser crystal, spectroscopic properties, sensitizing ion, deactivating ion
