TOP GUIDELINES OF ER:YB:YAB CRYSTAL

The nonradiative transition charges Keep to the system WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the Electricity gap. The nonradiative changeover prices of Er3+ show temperature dependence in step with the multiphonon leisure theory. In Tm3+ the temperature dependence of nonradiative rest premiums is challenging by the e
