A SECRET WEAPON FOR ER:YB:YAB CRYSTAL

The nonradiative transition prices Adhere to the system WNR = W (0) exp(-alphap), exactly where p is the volume of phonons matching the Vitality hole. The nonradiative changeover fees of Er3+ exhibit temperature dependence according to the multiphonon relaxation theory. In Tm3+ the temperature dependence of nonradiative rest premiums is complex bec
