GETTING MY ER:YB:YAB CRYSTAL TO WORK

The nonradiative transition charges follow the formula WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the energy gap. The nonradiative changeover charges of Er3+ show temperature dependence in line with the multiphonon leisure principle. In Tm3+ the temperature dependence of nonradiative peace rates is intricate through the
