LITTLE KNOWN FACTS ABOUT ER:YB:YAB CRYSTAL.

The nonradiative changeover charges Keep to the formula WNR = W (0) exp(-alphap), where by p is the quantity of phonons matching the Power hole. The nonradiative changeover charges of Er3+ show temperature dependence in step with the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative leisure fees is challenging via the exi
