FIELD: optical information recording, possible use for creating holographic optical elements.
SUBSTANCE: in accordance to method for recording information on amorphous chalcogenide film, including effect of laser radiation with energy exceeding width of forbidden zone, film is used based on germanium and gallium chalcogenides, which is produced by means of impulse laser spraying method.
EFFECT: production of high contrast information recording, increased resolution, cheaper information recording process.
