WHAT DOES ER:YB:YAB CRYSTAL MEAN?

The nonradiative changeover premiums follow the system WNR = W (0) exp(-alphap), where by p is the volume of phonons matching the Power hole. The nonradiative transition costs of Er3+ show temperature dependence per the multiphonon peace idea. In Tm3+ the temperature dependence of nonradiative rest rates is intricate from the existence of self-abso
