The velocities of the principal and several higher‐order elastic modes localized in CaF2 films grown epitaxially on Si(111) have been measured using Brillouin scattering. The effective elastic constants of the epilayers are evaluated from a fit to the mode dispersion. With decreasing film thicknesses from about 1500 Å reductions from the bulk elastic constants are found. Thicker films are well characterized by bulk parameters.
