5 SIMPLE TECHNIQUES FOR ER:YB:YAB CRYSTAL

The nonradiative transition premiums Keep to the method WNR = W (0) exp(-alphap), in which p is the volume of phonons matching the Strength hole. The nonradiative transition costs of Er3+ show temperature dependence in step with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative relaxation costs is complicated through
