Recording of polarization holograms in photodarkened amorphous As2S3 thin films

Not Accessible

Your library or personal account may give you access

Abstract

The inscription of polarization gratings in amorphous As2S3 thin films is shown to be accompanied by a scalar modulation of the same period. An exception is the (s + p) recording configuration where a pure polarization grating may be obtained even for relatively high photoexposures.
