GETTING MY ER:YB:YAB CRYSTAL TO WORK

The nonradiative transition rates follow the system WNR = W (0) exp(-alphap), exactly where p is the amount of phonons matching the energy gap. The nonradiative transition fees of Er3+ exhibit temperature dependence in keeping with the multiphonon rest theory. In Tm3+ the temperature dependence of nonradiative rest fees is sophisticated by the exis
