Paper Abstract

Computer generated holograms are used to create doughnut beams. We use negative-tone inorganic-organic hybrid SiO2: TiO2 glasses to fabricate computer-generated holograms. This sol-gel material enjoys an advantage over materials used in the conventional photoresist-based fabrication techniques in terms of a single-step etching-free process. The doughnut beams may be useful in making laser traps for precision measurements and for Bose-Einstein condensation.
