ER:YB:YAB CRYSTAL CAN BE FUN FOR ANYONE

The nonradiative transition charges follow the components WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the Electrical power hole. The nonradiative changeover rates of Er3+ exhibit temperature dependence in keeping with the multiphonon peace idea. In Tm3+ the temperature dependence of nonradiative peace rates is challenging
