Confirmation of the local nature of the plasma grating photorefractive effect.
Two-wave mixing measurements made during the encoding of plasma gratings in AlGaAs:Te indicate that there is no phase shift between the illumination intensity pattern and the encoded refractive-index grating. These results support our previously proposed photorefractive mechanism, which is based on persistent plasma gratings and does not require charge transport.
