Final Activity Report Summary - NMVHTS (New materials for volume holographic technologies)
The present project dealt with the research on new materials for volume holography-based technologies, as well as with the building of an optical setup for both recording and reading of multiplexed holograms and the study of the physical and chemical mechanisms of volume holographic recording in chalcogenide glasses. At the current stage, the optical setup had three degrees of freedom, namely one degree of translation, x, and two degrees of rotation, and non-polarising optics. It was planned to increase the degrees of freedom to five, including two more linear translation stages, namely y and z. A thermal evaporation chamber sample was customised for the deposition of antireflection coatings and a second evaporation chamber was being adapted for the preparation of thick films of amorphous chalcogenides by the time of the project completion. First tests were performed on two microns thick amorphous As40S60 and As20S80 films and the results probed both the stability of the system and the suitability of the chalcogenide films for the recording of extended focus Fresnel lenses as the first diffractive optical element which was planned to be addressed to improve the performance of laser cutting systems. On the other hand, a new continuous wave cw-laser-assisted film deposition technique was recently investigated, expected to reduce the film fabrication time and probably provide new film properties.

Цел на проекта
Volume holography brings attractive and unique technological applications related to its capability to store a number of holograms in the same volume of a light-sensitive material (multiplexing). Multifunction optical devices or holographic data storage me dia faster and bigger than conventional ones, are only two examples, among a variety of others, some of them unthought yet. Proposed research will cover the physical basis of the volume holographic recording and multiplexing, as well as physiochemical mech anisms occurring in new potentially suitable materials to be used in volume holographic technologies. To reach the outcome of the project, it is proposed to build a unique apparatus capable of concurrently recording and evaluating multiplexed holograms by different multiplexing methods. Chalcogenide glasses (e.g. compounds of S and/or Se with As and/or P) will be the first family of photosensitive materials to be studied. Even though the capability of these materials to store high-resolution light patterns, via the variety of photoinduced effects they exhibit, is well-known, the proposed specific research on volume holography still has not been carried out, and it is expected, therefore, to get high-impact results quite early. Thick chalcogenide films will b e deposited onto suitable substrates both by thermal evaporation and by spin coating of a solution of the bulk starting material in an organic solvent. The optimisation of these deposition techniques, in order to reach the standards required for volume hol ographic recording media, will be carried out.
