GETTING MY ER:YB:YAB CRYSTAL TO WORK

The nonradiative transition costs Keep to the formula WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the Electrical power gap. The nonradiative transition premiums of Er3+ show temperature dependence per the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative relaxation costs is complicated through t
