A SECRET WEAPON FOR ER:YB:YAB CRYSTAL

The nonradiative transition fees Keep to the formula WNR = W (0) exp(-alphap), where by p is the quantity of phonons matching the Vitality hole. The nonradiative changeover charges of Er3+ exhibit temperature dependence consistent with the multiphonon leisure theory. In Tm3+ the temperature dependence of nonradiative relaxation premiums is challeng
