THE BASIC PRINCIPLES OF ER:YB:YAB CRYSTAL

The nonradiative transition charges Stick to the components WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the energy hole. The nonradiative transition charges of Er3+ exhibit temperature dependence per the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative leisure premiums is sophisticated via the
