TOP GUIDELINES OF ER:YB:YAB CRYSTAL

The nonradiative changeover prices follow the system WNR = W (0) exp(-alphap), in which p is the number of phonons matching the Electrical power gap. The nonradiative changeover prices of Er3+ exhibit temperature dependence per the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative relaxation premiums is complicated
