LITTLE KNOWN FACTS ABOUT ER:YB:YAB CRYSTAL.

The nonradiative changeover rates Adhere to the method WNR = W (0) exp(-alphap), exactly where p is the volume of phonons matching the Power hole. The nonradiative transition charges of Er3+ show temperature dependence in line with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative peace charges is sophisticated with
