ER:YB:YAB CRYSTAL - AN OVERVIEW

The nonradiative transition premiums follow the formula WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the Electrical power gap. The nonradiative transition fees of Er3+ show temperature dependence per the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative rest costs is complicated through the exist
