… in the frame of photorefractive spatial-soliton propagation are exploited to derive a novel
scheme for the investigation of space-charge field formation in photorefractive crystals. The …

… To excite space charge waves, we used an Ar ion laser, λ = 514.5 nm . The average power
incident on the crystal was in the interval 100 – 150 mW ∕ cm 2 . One of the beams was …

… As usual for photorefractive crystals, we have assumed weak thermal excitation, validity
