ER:YB:YAB CRYSTAL - AN OVERVIEW

The nonradiative transition premiums Keep to the formula WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the Power hole. The nonradiative changeover charges of Er3+ show temperature dependence consistent with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative leisure fees is difficult because of
