THE BASIC PRINCIPLES OF ER:YB:YAB CRYSTAL

The nonradiative transition charges follow the method WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the Power hole. The nonradiative changeover rates of Er3+ exhibit temperature dependence per the multiphonon relaxation principle. In Tm3+ the temperature dependence of nonradiative peace premiums is complicated with the exist
