ER:YB:YAB CRYSTAL OPTIONS

The nonradiative transition fees Keep to the method WNR = W (0) exp(-alphap), in which p is the number of phonons matching the Electricity 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 from the existence of self
