High performance acousto-optic chalcogenide glass based on Ga2S3 La2S3 systems Academic Article uri icon


  • Abstract Chalcogenide glass systems based on Ga 2 S 3 La 2 S 3 (GLS glass), have been found to exhibit relatively high acousto-optic figures of merit, low acoustic loss and high acoustic velocity. These properties of the GLS glass combined with its transparency both in the visible and the infrared (0.5–10 μm), nontoxicity, high softening temperature (T g= 561 C), ease of fabrication, optical quality, chemical stability, and isotropic properties, make it attractive for acousto-optic device applications.
