Er3+/Yb3+/Pr3+:SrLaGaO4晶体的光谱分析及中红外发射增强
Spectroscopic Analysis and Mid-infrared Emission Enhancement in Er3+/Yb3+/Pr3+:SrLaGaO4 Crystal
摘要
Abstract
Crystals of Er3+/Yb3+/Pr3+:SrLaGaO4,Er3+/Yb3+:SrLaGaO4,and Er3+:SrLaGaO4 were successfully grown using the non-stoichiometric ratio Czochralski method,and detailed spectroscopic analyses were conducted.Addi-tionally,thermal performance analyses were performed on pure SrLaGaO4 crystals.Compared with Er3+:SrLaGaO4 crystal,Er3+/Yb3+/Pr3+:SrLaGaO4 crystal not only shows better absorption characteristics but also exhibits weaker near-infrared emissions,as well as superior mid-infrared emissions.Furthermore,the self-termination effect for the 2.7 μm erbium laser is suppressed successfully since the fluorescence lifetime of the 4I13/2 lower level of Er3+decreas-es markedly while that of the upper 4I11/2 level falls slightly in Er3+/Yb3+/Pr3+:SrLaGaO4 crystal.Besides,the sensitization effect of Yb3+ion and deactivation effect of Pr3+ion as well as the energy transfer mechanism in Er3+/Yb3+/Pr3+:SrLaGaO4 crystal were studied in this work.In conclusion,the introduction of Yb3+and Pr3+ions is favorable for achieving an enhanced 2.7 μm emission in Er3+/Yb3+/Pr3+:SrLaGaO4 crystal which can act as a promising candidate for mid-infra-red lasers.关键词
