Formfactor of a hologram on a chalcogenide glassy semiconductor and azopolymer

In this work, the formfactor influence on the diffraction efficiency of 2D and 3D phase holograms was analyzed. Experimental results showed that holograms recorded in a chalcogenide glassy semiconductor and an azopolymer have limitations on maximum achievable diffraction efficiency. The coefficient...

Summary:In this work, the formfactor influence on the diffraction efficiency of 2D and 3D phase holograms was analyzed. Experimental results showed that holograms recorded in a chalcogenide glassy semiconductor and an azopolymer have limitations on maximum achievable diffraction efficiency. The coefficient of optimal exposure increase that is necessary to achieve maximum achievable diffraction efficiency was obtained. Due to the difference between the values of the formfactor in the case of the Raman-Nath diffraction and of that in the case of the Bragg diffraction for diffraction on thin (2D) holograms, the value of the formfactor turned out to be larger than that for diffraction on volume (3D) phase holograms.
