Abstract

Theoretically predicted hard excitation of optical hexagons in photorefractive crystals is studied experimentally in barium titanate. The well-developed hysteresis loop is discovered in the dependence of the hexagon intensity on the crystal coupling strength proving the hard mode of the oscillation onset. The analogy of the excitation threshold for optical hexagon and first order optical phase transition is revealed.
