Diffraction by Holographic Gratings in Diacetylene Crystals

Vogtmann, Th. / Bauer, H.-D. / Müller, Irene / Schwoerer, M.

Abstract The topochemical solid-state UV-photopolymerization of diacetylenes has been used to write holographic gratings in macroscopic TS6 single crystals. For visible light (633nm) these gratings act as thick volume phase gratings, showing efficiencies up to 63% and a small angular selectivity halfwidth down to 0.12°, which has been used to store 77 gratings simultaneously within one sample. The dependence of angular selectivity on sample thickness and UV-penetration depth for crystals with different polymer content is discussed and compared to simulations. Sensitivity, resolution, Q- and ρ-factors are given together with an analysis of the modulation amplitudes.
