THE BEST SIDE OF ER:YB:YAB CRYSTAL

The nonradiative transition rates Keep to the components WNR = W (0) exp(-alphap), the place p is the quantity of phonons matching the Electrical power gap. The nonradiative changeover prices of Er3+ exhibit temperature dependence in step with the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative leisure prices is complic
