GETTING MY ER:YB:YAB CRYSTAL TO WORK

The nonradiative transition fees Keep to the method WNR = W (0) exp(-alphap), in which p is the volume of phonons matching the Vitality hole. The nonradiative transition fees of Er3+ exhibit temperature dependence in keeping with the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative relaxation charges is complicated
