Two-wavelength holographic recording in ruthenium-doped Bi<inf>12</inf>SiO<inf>20</inf> crystal at near-infrared spectral range

Abstract

In this paper, we report our investigations on real-time holographic recoding at 1064 nm in Ru-doped bismuth sillenite crystal with a green gating light at 532 nm. By using gating light significant improvement of the response time to 80 ms is achieved and the prolonged read-out process of the recorded hologram is observed.
