GETTING MY ER:YB:YAB CRYSTAL TO WORK

The nonradiative changeover premiums Keep to the formula WNR = W (0) exp(-alphap), wherever p is the amount of phonons matching the Electrical power gap. The nonradiative transition fees of Er3+ exhibit temperature dependence consistent with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative peace rates is challengin
