Abstract

Holographic optical elements (HOEs) play a key role in the optical processing and optical computing fields as well as in non-destructive holographic testing studies. The fabrication of such linear and nonlinear HEOs requires high quality recording films; in the search of such a recording material, we studied photocrosslinking colloid systems like dichromated polyvinyl alcohol films (DC-PVAL). Those films gave holograms having a maximum diffraction efficiency value (MDE) of 18% at 488 nm; at 442 nm, we obtained MDE values between 20% and 55%. When adding a xanthene dye, the MDE value may be increased. In the present communication we introduce many new results on hologram recordings with another kind of xanthene dye dichromated colloid film at 442 nm. Also the knowledge of characteristic properties of such xanthene dye DC-colloids films permits us to focus on `How they are usable in engineering applications.'
