| Abstract: | Absorption, flourescence spectra of E r 3+ ions, and flourescent decay curvels of 4I 11/2 and 4I 13/2 levels in 2 at.%Er: YAG crystal were measured. we have got flourescent Lifetimes τ 0and microparameters C DA ,and r 0which describe the interaction between ions and ions,fitting in with flourescent decay curves.Substituting τ 0and r 0into the approximate equation for optimal concentrations,which wes deduced from one of authors,we calculated out optimal concentrations of E 3+ r ions in YAG crystal,and compared with experiment results. |
