摘要
本文对Er离子掺杂浓度分别为1wt-%和50wt-%的Er:YAG晶体的吸收谱和红外光致发光谱进行了比较性研究。掺杂浓度不同,其吸收谱的概貌基本相同。而红外光致发光谱中,发射带强度随浓度升高而增强。发射带中,在1.6μm附近,1wt-%样品峰值位置与50wt-%样品峰谷位置重合。晶体中因Er离子浓度增大而显示出自吸收和交叉驰豫现象。同时讨论了Er:YAG晶体中激光振荡的机制。)GeLiangYangBaochengLinYuanqi(DepartmentofPhysics,EastChinaNormalUniversity,Shanghai200062,China)(DepertmentofPhysics,TongjiUniversity,Shanghai,200092,China)LiFengyu(ShanghaiInstituteofOpticsandFineMechanics,AcademiaSinica,Shanghai201800,China)(Received19Januuary1993,accepted15October1993)AbstractAcomparativestudyonthetr?
