ER:YB:YAB CRYSTAL OPTIONS

The nonradiative changeover prices Adhere to the formula WNR = W (0) exp(-alphap), where by p is the quantity of phonons matching the energy gap. The nonradiative changeover prices of Er3+ exhibit temperature dependence in line with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative relaxation costs is complex because
