Paper Abstract

In this work we demonstrate direct writing of a computer generated hologram using optical damage in glass as a possible recording process. The recording was performed by ablation in BK7 optical glass. We used a 10 Hz, 35 picoseconds, 5 mJ Nd:YAG pulse focused using a lens to create 50 μm spots. It was observed that the material surrounding the damage spot was altered producing a 70 μm minimum pixel resolvable separation by induced birrefringence.
