THE BASIC PRINCIPLES OF ER:YB:YAB CRYSTAL

The nonradiative transition premiums Stick to the components WNR = W (0) exp(-alphap), wherever p is the number of phonons matching the Power hole. The nonradiative transition costs of Er3+ show temperature dependence according to the multiphonon rest concept. In Tm3+ the temperature dependence of nonradiative leisure fees is difficult through the
