A SECRET WEAPON FOR ER:YB:YAB CRYSTAL

The nonradiative changeover rates Adhere to the components WNR = W (0) exp(-alphap), wherever p is the amount of phonons matching the Power hole. The nonradiative changeover premiums of Er3+ exhibit temperature dependence consistent with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative rest fees is intricate from the
