5 SIMPLE TECHNIQUES FOR ER:YB:YAB CRYSTAL

The nonradiative transition premiums Keep to the system WNR = W (0) exp(-alphap), wherever p is the amount of phonons matching the Power hole. The nonradiative changeover charges of Er3+ show temperature dependence according to the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative peace prices is complex from the existe
