摘要：

Novel phenomena: large photo-induced anisotropy without any photo-darkening, photo-induced gyrotropy (circular dichroism and birefringence) and photo-induced light scattering accompanied by depolarization have been discovered in As2S3 chalcogenide glass on exposure to below-band-gap polarized light. Maxima for all these phenomena are observed in As34S52I14 glass. Optical and thermal reversibility of these effects has been established and studied. The photo-induced phenomena are attributed to interaction of light with weak chemical bonds leading to creation or re-orientation of anisotropic and gyrotropic scatterers.
