A SECRET WEAPON FOR ER:YB:YAB CRYSTAL

The nonradiative transition premiums Adhere to the components WNR = W (0) exp(-alphap), exactly where p is the number of phonons matching the Power gap. The nonradiative transition fees of Er3+ show temperature dependence per the multiphonon rest theory. In Tm3+ the temperature dependence of nonradiative relaxation rates is sophisticated via the ex
