ER:YB:YAB CRYSTAL - AN OVERVIEW

The nonradiative changeover premiums follow the method WNR = W (0) exp(-alphap), where p is the number of phonons matching the Power gap. The nonradiative changeover premiums of Er3+ show temperature dependence in keeping with the multiphonon leisure concept. In Tm3+ the temperature dependence of nonradiative relaxation rates is complex via the exi
