Mid-IR Spectroscopic Study of Low-Phonon Er3+ doped BaF2 Single Crystals (JTu5A.15)

Presenter: Ei Ei Brown, US Army Research Laboratory

Mid-infrared (3-5 um) spectroscopic properties of Er3+:BaF2 are reported. An analysis of the temperature dependence of the 4.5 um fluorescence lifetime revealed that the 4I9/2 state exhibited a multiphonon relaxation contribution.
