WHAT DOES ER:YB:YAB CRYSTAL MEAN?

The nonradiative changeover charges follow the components WNR = W (0) exp(-alphap), wherever p is the amount of phonons matching the energy hole. The nonradiative changeover prices of Er3+ exhibit temperature dependence according to the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative leisure prices is difficult be
