ER:YB:YAB CRYSTAL OPTIONS

The nonradiative changeover charges Stick to the formula WNR = W (0) exp(-alphap), in which p is the quantity of phonons matching the Vitality gap. The nonradiative transition costs of Er3+ exhibit temperature dependence consistent with the multiphonon rest idea. In Tm3+ the temperature dependence of nonradiative peace costs is complicated through
