5 SIMPLE TECHNIQUES FOR ER:YB:YAB CRYSTAL

The nonradiative transition premiums Stick to the components WNR = W (0) exp(-alphap), wherever p is the amount of phonons matching the Electrical power gap. The nonradiative changeover costs of Er3+ show temperature dependence according to the multiphonon relaxation principle. In Tm3+ the temperature dependence of nonradiative peace prices is soph
