Spectral selectivity investigation of volume holograms by means of laser radiation

Abstract

A broadband laser-based technique for investigation the parameters of spectral selectivity high-selective volume hologram is suggested. The studies, carried out by this method, were realized with using radiation of femtosecond and semiconductor lasers. The transmission phase holographic gratings recorded on polymer recording media samples of 1-2 mm thickness were used. The results of investigations of spectral selectivity of transmission phase holographic gratings of various frequencies are presented. The verification of obtained results was fulfilled. The limits of technique validity were estimated.
