ER:YB:YAB CRYSTAL OPTIONS

The nonradiative changeover charges Stick to the system WNR = W (0) exp(-alphap), the place p is the number of phonons matching the Electricity gap. The nonradiative transition costs of Er3+ show temperature dependence in step with the multiphonon peace principle. In Tm3+ the temperature dependence of nonradiative leisure prices is challenging from
