THE BEST SIDE OF ER:YB:YAB CRYSTAL

The nonradiative transition prices Adhere to the components WNR = W (0) exp(-alphap), the place p is the volume of phonons matching the energy gap. The nonradiative changeover costs of Er3+ show temperature dependence in step with the multiphonon rest idea. In Tm3+ the temperature dependence of nonradiative rest rates is sophisticated with the exis
