THE BEST SIDE OF ER:YB:YAB CRYSTAL

The nonradiative transition costs Adhere to the method WNR = W (0) exp(-alphap), exactly where p is the quantity of phonons matching the energy gap. The nonradiative transition charges of Er3+ exhibit temperature dependence per the multiphonon peace principle. In Tm3+ the temperature dependence of nonradiative rest charges is sophisticated via the
