A REVIEW OF ER:YB:YAB CRYSTAL

The nonradiative transition premiums Stick to the formula WNR = W (0) exp(-alphap), wherever p is the amount of phonons matching the Electrical power gap. The nonradiative changeover rates of Er3+ show temperature dependence consistent with the multiphonon peace idea. In Tm3+ the temperature dependence of nonradiative peace charges is complicated w
