THE BASIC PRINCIPLES OF ER:YB:YAB CRYSTAL

The nonradiative changeover fees Keep to the formula WNR = W (0) exp(-alphap), wherever p is the number of phonons matching the Electricity hole. The nonradiative transition costs of Er3+ exhibit temperature dependence according to the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative leisure fees is challenging by
