5 SIMPLE STATEMENTS ABOUT ER:YB:YAB CRYSTAL EXPLAINED

The nonradiative changeover fees follow the formula WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the Power hole. The nonradiative changeover rates of Er3+ exhibit temperature dependence according to the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative rest premiums is complicated with the
