5 SIMPLE TECHNIQUES FOR ER:YB:YAB CRYSTAL

The nonradiative transition charges follow the method WNR = W (0) exp(-alphap), in which p is the volume of phonons matching the Vitality hole. The nonradiative changeover rates of Er3+ exhibit temperature dependence in keeping with the multiphonon relaxation idea. In Tm3+ the temperature dependence of nonradiative rest costs is complicated through
