THE BEST SIDE OF ER:YB:YAB CRYSTAL

The nonradiative changeover premiums Keep to the formula WNR = W (0) exp(-alphap), wherever p is the amount of phonons matching the Electrical power gap. The nonradiative transition premiums of Er3+ show temperature dependence according to the multiphonon rest idea. In Tm3+ the temperature dependence of nonradiative relaxation charges is sophistica
