5 SIMPLE STATEMENTS ABOUT ER:YB:YAB CRYSTAL EXPLAINED

The nonradiative changeover charges follow the system WNR = W (0) exp(-alphap), in which p is the amount of phonons matching the Power hole. The nonradiative changeover prices of Er3+ show temperature dependence according to the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative relaxation charges is complicated with the
