ER:YB:YAB CRYSTAL - AN OVERVIEW

The nonradiative transition costs Stick to the method WNR = W (0) exp(-alphap), in which p is the number of phonons matching the energy hole. The nonradiative changeover rates of Er3+ exhibit temperature dependence according to the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative leisure premiums is complex with th
