A SECRET WEAPON FOR ER:YB:YAB CRYSTAL

The nonradiative transition charges Keep to the formulation WNR = W (0) exp(-alphap), exactly where p is the amount of phonons matching the Power gap. The nonradiative changeover premiums of Er3+ show temperature dependence per the multiphonon rest theory. In Tm3+ the temperature dependence of nonradiative peace premiums is complicated because of t
