THE BASIC PRINCIPLES OF ER:YB:YAB CRYSTAL

The nonradiative changeover rates Adhere to the system WNR = W (0) exp(-alphap), where by p is the quantity of phonons matching the Power gap. The nonradiative changeover rates of Er3+ exhibit temperature dependence in keeping with the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative rest premiums is complex throug
