The three refractive indices for the monoclinic crystal BaY2F8 have been measured as function of the wavelength from 275 nm to 2.65 micron, and the position of the index ellipsoid has been determined. Most energy levels with energy less than 25,000 per cm have been determined from low-temperature spectroscopic data for Pr3, Dy3, Ho3, and Er3 in this structure. Further, the room-temperature fluorescence lifetimes have been measured for some of the multiplets of these four doping ions. Author
