A REVIEW OF ER:YB:YAB CRYSTAL

The nonradiative changeover rates Adhere to the method WNR = W (0) exp(-alphap), in which p is the volume of phonons matching the Vitality gap. The nonradiative changeover rates of Er3+ exhibit temperature dependence in step with the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative leisure fees is challenging by the exis
