WHAT DOES ER:YB:YAB CRYSTAL MEAN?

The nonradiative transition rates Adhere to the components WNR = W (0) exp(-alphap), in which p is the quantity of phonons matching the Power hole. The nonradiative changeover charges of Er3+ exhibit temperature dependence in step with the multiphonon rest idea. In Tm3+ the temperature dependence of nonradiative rest charges is challenging because
