TOP GUIDELINES OF ER:YB:YAB CRYSTAL

The nonradiative changeover prices follow the formula WNR = W (0) exp(-alphap), exactly where p is the volume of phonons matching the Electrical power gap. The nonradiative changeover costs of Er3+ show temperature dependence per the multiphonon peace principle. In Tm3+ the temperature dependence of nonradiative relaxation charges is sophisticated
