ER:YB:YAB CRYSTAL OPTIONS

The nonradiative transition premiums follow the system WNR = W (0) exp(-alphap), the place p is the volume of phonons matching the Strength hole. The nonradiative transition fees of Er3+ exhibit temperature dependence in keeping with the multiphonon relaxation theory. In Tm3+ the temperature dependence of nonradiative peace rates is intricate by th
