A SIMPLE KEY FOR ER:YB:YAB CRYSTAL UNVEILED

The nonradiative changeover costs follow the method WNR = W (0) exp(-alphap), the place p is the number of phonons matching the Electrical power hole. The nonradiative changeover rates of Er3+ show temperature dependence in line with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative relaxation fees is difficult by the
