The cascade conical diffraction phenomenon from up to four crystals is experimentally demonstrated. Less than one year ago M.V. Berry predicted that the focus pattern of conical diffraction from an N-crystal cascade is the superposition of 2N−1 single-crystal concentric conical diffraction patterns (rings), whose ring radii are a combination of those from the individual crystals in cascade. The experimental observations presented here are in full agreement with these theoretical predictions.
