Slowing down of light in photorefractive crystals with beam intensity coupling reduced to zero.
A considerable deceleration of light pulses in crystals with nearly compensated space-charge field proves that the strong dispersion of dynamic photorefractive gratings in the vicinity of Bragg resonance is of primary importance for light slowing down.
