ER:YB:YAB CRYSTAL - AN OVERVIEW

The nonradiative changeover fees follow the method WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the Strength gap. The nonradiative transition fees of Er3+ exhibit temperature dependence in keeping with the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative rest fees is intricate from the exis
