GETTING MY ER:YB:YAB CRYSTAL TO WORK

The nonradiative changeover costs follow the components WNR = W (0) exp(-alphap), exactly where p is the number of phonons matching the Power gap. The nonradiative transition premiums of Er3+ show temperature dependence consistent with the multiphonon peace concept. In Tm3+ the temperature dependence of nonradiative peace premiums is difficult by t
