A SECRET WEAPON FOR ER:YB:YAB CRYSTAL

The nonradiative transition rates follow the method WNR = W (0) exp(-alphap), in which p is the volume of phonons matching the Strength hole. The nonradiative changeover prices of Er3+ exhibit temperature dependence consistent with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative leisure premiums is complicated thr
