Holographic data storage on nonphotosensitive glass with a single femtosecond laser pulse

Holographic data storage on fused silica, soda-lime, and lead glasses with a single 130 fs laser pulse at a wavelength of 800 nm is presented. After the sample is exposed to the interference fringe pattern of the object beam and the reference beam, a relief microhologram is recorded through surface ablation. The recorded information can be reconstructed without destruction of the hologram when the power of the reference beam is reduced below the ablation threshold. The preliminary experimental results demonstrate the possibility of holographic data storage on nonphotosensitive glasses.
