THE BEST SIDE OF ER:YB:YAB CRYSTAL

The nonradiative changeover costs Adhere to the system WNR = W (0) exp(-alphap), the place p is the amount of phonons matching the Strength hole. The nonradiative transition charges of Er3+ show temperature dependence in line with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative peace costs is complicated through t
