WHAT DOES ER:YB:YAB CRYSTAL MEAN?

The nonradiative transition costs Stick to the formula WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the Power gap. The nonradiative changeover rates of Er3+ exhibit temperature dependence in keeping with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative relaxation costs is complicated from the
