    Abstract:
    The spatial dynamics of the photo-induced surface relief and phase gratings in As2S3 glass are described. Excursion amplitudes up to 150 nm and grating efficiencies up to 27% are observed. Depth and resolution limits for the effect are measured and a model for the resolution limit is proposed.
