5 SIMPLE TECHNIQUES FOR ER:YB:YAB CRYSTAL

The nonradiative transition costs Adhere to the method WNR = W (0) exp(-alphap), exactly where p is the quantity of phonons matching the Power hole. The nonradiative changeover rates of Er3+ exhibit temperature dependence in keeping with the multiphonon leisure theory. In Tm3+ the temperature dependence of nonradiative rest premiums is complicated
