YAG:Ce,Er晶体的光学性能

The Optical Properties of Ce^(3+),Er^(3+)Codoped YAG Crystal

根据测试的 YAG:Ce,Er 晶体的吸收谱,计算了吸收截面等光学参量.由Ce^(3+)对 Er^(3+)离子能态上布居数的影响,讨论 Ce^(3+)对 Er^(3+)的敏化作用。

The optical parameters such as the absorptive cross-sections et.al.are calculated on the basis of measured absorption spectra of YAG:Ce,Er and YAD:Er crystals.The sensitive ef- fects of cesium ions on erbium ions are discussed according to the influence of cesium ions on the populations of levels(~4Ⅰ_(12/2),~4Ⅰ_(13/2)~4Ⅰ_(15/2))of erbium ions.
