5 SIMPLE TECHNIQUES FOR ER:YB:YAB CRYSTAL

The nonradiative changeover charges follow the system WNR = W (0) exp(-alphap), in which p is the quantity of phonons matching the Power hole. The nonradiative changeover prices of Er3+ show temperature dependence in line with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative relaxation charges is sophisticated throug
