Lm. Voskovtsova et al., FEATURES OF HOLOGRAM DIFFRACTION-GRATING REPLICAS MADE FROM VITREOUS CHALCOGENIDE SEMICONDUCTORS, Soviet journal of optical technology, 60(9), 1993, pp. 617-619
Features of the replication of hologram diffraction gratings fabricate
d using a light-sensitive material based on vitreous chalcogenide semi
conductors are investigated. It is shown that the line profile of the
hologram diffraction grating differs from the calculated sinusoidal pr
ofile; this leads to a difference in the spectral diffraction efficien
cy of different generations of replicas. The replicas are inferior to
the grating die on the average by a factor of 1.5-2.0 in terms of the
scattered light level.
