ER:YB:YAB CRYSTAL - AN OVERVIEW

The nonradiative changeover charges follow the method WNR = W (0) exp(-alphap), exactly where p is the amount of phonons matching the energy gap. The nonradiative changeover prices of Er3+ show temperature dependence in line with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative rest costs is complicated with the exis
