THE BASIC PRINCIPLES OF ER:YB:YAB CRYSTAL

The nonradiative changeover fees Keep to the formula WNR = W (0) exp(-alphap), in which p is the volume of phonons matching the Electrical power hole. The nonradiative changeover prices of Er3+ show temperature dependence in line with the multiphonon leisure principle. In Tm3+ the temperature dependence of nonradiative peace rates is difficult beca
