THE BASIC PRINCIPLES OF ER:YB:YAB CRYSTAL

The nonradiative transition premiums Adhere to the formulation WNR = W (0) exp(-alphap), where by p is the quantity of phonons matching the Vitality hole. The nonradiative transition charges of Er3+ show temperature dependence in step with the multiphonon peace concept. In Tm3+ the temperature dependence of nonradiative leisure prices is complicate
