THE BEST SIDE OF ER:YB:YAB CRYSTAL

The nonradiative transition costs follow the system WNR = W (0) exp(-alphap), the place p is the number of phonons matching the Electrical power gap. The nonradiative changeover fees of Er3+ exhibit temperature dependence in keeping with the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative leisure rates is intricat
