TREVINO-PALACIOS, Carlos Gerardo; ZAPATA-NAVA, Oscar Javier y OLIVARES-PEREZ, Arturo. Optical damage as a computer generated hologram recording mechanism. J. appl. res. technol [online]. 2015, vol.13, n.6, pp.591-595. ISSN 2448-6736. https://doi.org/10.1016/j.jart.2015.10.015.
In this paper we report optical damage as a bulk glass recording process. We used a 10 Hz, 35 picoseconds, 5 mJ polarized Nd:YAG pulse laser focused using a 25 mm lens to create 50 μm average optical damage spots to record a computer generated hologram embedded in stress free BK-7 glass. It was observed that for the recording conditions the material surrounding the damage spot was induced birefringence altered producing a 70 μm pixel optimal separation.
