AbstractAs-S-Se chalcogenide thin films are successfully employed in classical and dot-matrix holography as inorganic photoresists for obtaining a relief-phase hologram. However using these films for image-matrix hologram recording has not been studied due to some features of image-matrix technology. For the applied research of the optical properties of As-S-Se films an experimental device of digital image-matrix holographic recording based on 100 mW 405 nm semi-conductor laser and Spatial Light Modulator (SLM) has been created. The device has the following main parameters: 140 × 105 µm frame size; laser intensity during exposure 10 W/cm2. With the help of this device diffraction grating and security holograms were recorded on As-S-Se thin films. The work reported herein presents results of an experimental study of how diffraction efficiency (DE) of the received relief-phase holographic gratings depends on an exposure and period. Diffraction grating profiles and speed of etching corresponding to different exposure doses are shown. Hologram samples with DE = 65% have been received which allows for using chalcogenide film as alternative to organic photoresists in applied dot-matrix and image-matrix holography.

Area Of Application

Essential improvement of the photorefractive parameters of theorganicstructures has been found via nano- and biostructuring process. The spectral and self-assembling features which can support the photorefractive effect of some conjugated materials, including the liquid crystal ones, have been presented. To investigate the laser-induced change of the refractive index of the nano- and bio-objects-doped materials the holographic recording technique has been used. Moreover some innovative perspective dyes have been applied to study the effect of the rotation of the polarization plane of light. The area of application of the modified materials has been discussed. The tendency to replace the nanotechnology process with the biotechnology ones has been predicted.
