摘　　要：3~5μm中红外激光在光电对抗、激光医疗、有害气体探测等领域具有重要的应用。以稀土离子掺杂的晶体作为增益介质可实现中红外激光输出,其中镝掺杂硫镓铅(Dy∶PbGa_(2)S_(4),Dy∶PGS)晶体具有相对较低的声子能量和较大的电子能隙,是一种性能优良、具有潜在应用价值的中红外激光介质材料。本文综述了中红外Dy∶PGS固体激光器的研究进展,重点介绍了在不同波长泵浦下的连续或脉冲激光输出特性,并对其未来发展方向进行了探讨。Mid-infrared laser at 3-5μm has important applications in the fields of photoelectric countermeasures,laser medical treatment,harmful gas detection.Rare earth ion doped crystal can be used as gain medium to realize mid-infrared laser output.Dysprosium doped lead thiogallate(Dy∶PbGa_(2)S_(4),Dy∶PGS)crystal is a mid-infrared laser medium material with excellent performance and potential application value under the advantages of relatively low phonon energy and large electron energy gap.In this paper,the research progress of mid-infrared Dy∶PGS solid state lasers is reviewed,with emphasis on the output characteristics of continuous or pulsed lasers pumped at different wavelengths,and its future development directions are discussed.
