THE BEST SIDE OF ER:YB:YAB CRYSTAL

The nonradiative changeover rates Adhere to the method WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the Power gap. The nonradiative transition charges of Er3+ show temperature dependence per the multiphonon peace idea. In Tm3+ the temperature dependence of nonradiative peace rates is intricate by the existence of self-absor
