Effective Holographic Record on Thin Films of Chalcogenide Semiconductors
Abstract
In this work is presented the research on thin films of chalcogenide glassy semiconductors as the medium for relief holograms record. The optimization of photoresist has allowed for an essential rise in sensitivity to light. As(50)Se(50) photoresist composition on which above thousandfold chemical amplification of holographic record is achieved, was used. Diffraction gratings in range of spatial frequencies 600 - 2400 mm are submitted. For natural light the magnitude of diffraction efficiency exceeds 70 - 80 % at measurements in autocollimator conditions. The probable cause of differences between continuous and pulse irradiation of thin films of chalcogenide vitreous semiconductors is discussed.
