from such material.
KDP crystals, including one with very large size.
18. TECHNIQUE OF PLANAR
PERIODICALLY-POLED STRUCTURES
(PPS) FABRICATION
Ferroelectric domain inverted
gratings were fabricated by a
set of local e-beam irradiations
in a scanning electron Schematic presentation of direct e-beam
writing upon Y-cut surface by the set
microscope with the use of the local irradiations to fabricate a planar
NanoMaker program to domain grating
construct the set of
irradiations and to vary doses
of them.

crystal that was chemically
etched.
Application of this method
doesn’t permit further use of
crystal as radiation converter.
