Cr 3 + , Nd 3 + multisites , pairs and energy transfer processes in laser crystal YAlO 3

Abstract

Detailed spectroscopic studies of YA103:Nd, YAl0,:Cr and YA103:Nd,Cr have shown that these crystals contain up to eight Nd3+ multisites and three C?' ones. C?' 4 Nd3' energy transfer is observed between various multisites and is starting from 2E C? energy level. C? donor decay can be adequately fit with the standard Inokuti-Hirayama theory but an assumption… (More)
