5 SIMPLE TECHNIQUES FOR ER:YB:YAB CRYSTAL

The nonradiative transition prices follow the system WNR = W (0) exp(-alphap), the place p is the number of phonons matching the Electricity hole. The nonradiative transition fees of Er3+ exhibit temperature dependence according to the multiphonon relaxation theory. In Tm3+ the temperature dependence of nonradiative leisure rates is challenging via
