5 SIMPLE STATEMENTS ABOUT ER:YB:YAB CRYSTAL EXPLAINED

The nonradiative changeover charges Keep to the method WNR = W (0) exp(-alphap), in which p is the quantity of phonons matching the Vitality hole. The nonradiative changeover premiums of Er3+ exhibit temperature dependence consistent with the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative rest charges is difficul
