A SIMPLE KEY FOR ER:YB:YAB CRYSTAL UNVEILED

The nonradiative changeover prices follow the method WNR = W (0) exp(-alphap), where p is the amount of phonons matching the Electrical power gap. The nonradiative changeover rates of Er3+ exhibit temperature dependence consistent with the multiphonon rest idea. In Tm3+ the temperature dependence of nonradiative peace prices is complex with the exi
