THE BASIC PRINCIPLES OF ER:YB:YAB CRYSTAL

The nonradiative transition premiums Adhere to the method WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the Vitality hole. The nonradiative changeover charges of Er3+ show temperature dependence in line with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative relaxation charges is sophisticated b
