THE BEST SIDE OF ER:YB:YAB CRYSTAL

The nonradiative changeover charges follow the system WNR = W (0) exp(-alphap), in which p is the amount of phonons matching the energy hole. The nonradiative changeover prices of Er3+ exhibit temperature dependence consistent with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative peace prices is sophisticated from
