Abstract

Simple photopolymer based on pentaerythritol tetrakis [3-mercaptopropionate] (PETMP) dispersed in Cellulose Acetate Butyrate (CAB) binder is developed to make surface and volume phase patterns transferred by means of a Direct Laser Writing (DLW) using 405nm laser. 1D and 2D gratings, as well as complex Computer Generated Holograms (CGHs) are printed and fully characterized exploiting different imaging techniques, including digital holography to highlight the contribution of surface phase shift and volume phase shift. Moreover, the diffraction efficiency of gratings is measured and correlated to the writing conditions.
