A REVIEW OF ER:YB:YAB CRYSTAL

The nonradiative transition premiums Stick to the components WNR = W (0) exp(-alphap), the place p is the quantity of phonons matching the Power hole. The nonradiative changeover rates of Er3+ exhibit temperature dependence in keeping with the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative rest premiums is complex beca
