A new technique for forming holographic grating has been proposed using the effect of the laser single beam on the light-sensitive layer deposited on the plane-parallel ZnS crystal plate containing packing defects. The technique is based on an existence of additional light beams in both reflected light and that transmitting through the crystal arising due to the laser beam reflection from boundaries of different polytype layers. The technique simplicity makes it possible to form gratings of various small periods (upto 4000 grooves*mm-1). The gratings can be used as test references in optical and electron microscopy.
