ER:YB:YAB CRYSTAL - AN OVERVIEW

The nonradiative transition fees follow the components WNR = W (0) exp(-alphap), the place p is the volume of phonons matching the Strength hole. The nonradiative transition premiums of Er3+ exhibit temperature dependence according to the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative relaxation prices is sophisticat
