ER:YB:YAB CRYSTAL - AN OVERVIEW

The nonradiative changeover charges follow the system WNR = W (0) exp(-alphap), the place p is the amount of phonons matching the Electrical power gap. The nonradiative changeover rates of Er3+ exhibit temperature dependence in keeping with the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative leisure rates is intri
