5 SIMPLE TECHNIQUES FOR ER:YB:YAB CRYSTAL

The nonradiative changeover premiums Keep to the method WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the Electrical power hole. The nonradiative transition charges of Er3+ show temperature dependence in keeping with the multiphonon rest theory. In Tm3+ the temperature dependence of nonradiative leisure fees is difficult be
