NOT KNOWN DETAILS ABOUT ER:YB:YAB CRYSTAL

The nonradiative changeover rates follow the components WNR = W (0) exp(-alphap), wherever p is the number of phonons matching the Vitality hole. The nonradiative changeover fees of Er3+ exhibit temperature dependence in line with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative rest costs is complex with the existen
