THE BASIC PRINCIPLES OF ER:YB:YAB CRYSTAL

The nonradiative transition charges follow the system WNR = W (0) exp(-alphap), in which p is the volume of phonons matching the Vitality hole. The nonradiative changeover prices of Er3+ exhibit temperature dependence according to the multiphonon relaxation idea. In Tm3+ the temperature dependence of nonradiative relaxation rates is challenging bec
