ER:YB:YAB CRYSTAL - AN OVERVIEW

The nonradiative changeover costs Keep to the components WNR = W (0) exp(-alphap), in which p is the number of phonons matching the Power gap. The nonradiative changeover costs of Er3+ exhibit temperature dependence consistent with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative relaxation charges is complicated via
