ER:YB:YAB CRYSTAL - AN OVERVIEW

The nonradiative transition costs follow the formula WNR = W (0) exp(-alphap), the place p is the number of phonons matching the energy gap. The nonradiative changeover prices of Er3+ exhibit temperature dependence in line with the multiphonon relaxation principle. In Tm3+ the temperature dependence of nonradiative rest rates is complex by the exis
