The coupling of diffraction and optical coherence of a three-level medium in an optical cavity is considered. Self-organisation and pattern formation due to a combination of electromagnetically induced transparency, close-to-resonance Kerr effects and diffraction is demonstrated. Self-focusing in the peaks of the resulting Turing pattern leads to localised amplification of the input pump. Spatial dissipative solitons with controllable position, dispersion and coherence are also described.
