Real-time holographic information processing at near infrared using ruthenium-doped bismuth sillenite crystals

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. We also demonstrate quasi-permanent holographic recording of image with fast speed in Ru-doped BSO crystal using two-wavelength recording.
