A SECRET WEAPON FOR ER:YB:YAB CRYSTAL

The nonradiative changeover premiums Stick to the components WNR = W (0) exp(-alphap), wherever p is the quantity of phonons matching the energy gap. The nonradiative changeover fees of Er3+ exhibit temperature dependence in keeping with the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative rest rates is difficult because
