NOT KNOWN FACTUAL STATEMENTS ABOUT ER:YB:YAB CRYSTAL

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