THE BASIC PRINCIPLES OF ER:YB:YAB CRYSTAL

The nonradiative changeover charges follow the system WNR = W (0) exp(-alphap), wherever p is the number of phonons matching the Electricity hole. The nonradiative transition costs of Er3+ show temperature dependence in line with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative peace fees is difficult via the existen
