Group delay dispersion measurement of Yb3+:YAl3(BO3)4 crystal with white-light interferometry

We report the group delay dispersion of Yb3+:YAl3(BO3)4 (Yb:YAB) crystal measured by a white-light interferometer, and compare with that calculated from the Sellmeier formulae provided by the crystal supplier, over the wavelength range from 1000 nm to 1080 nm. The data should be useful for the dispersion compensation for femtosecond pulse generation in Yb:YAB lasers.
