A SIMPLE KEY FOR ER:YB:YAB CRYSTAL UNVEILED

The nonradiative transition charges follow the components WNR = W (0) exp(-alphap), wherever p is the amount of phonons matching the Electrical power gap. The nonradiative changeover prices of Er3+ exhibit temperature dependence in line with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative relaxation charges is sophi
