Abstract
We analyze the superradiant emission with and without inversion from a thin film comprised of three-level atoms with the A-scheme of operating transitions. Since the thickness of the system is assumed to be smaller than the emission wavelength, the local-field correction to the acting field becomes of great importance and affects the three-level superradiance to a large extent. Due to this correction, a competition between the operating transitions occurs, resulting under suitable conditions in the suppression of one of them.
