BSO (Bismuth Silicon Oxide) is a photorefractive crystal that has been extensively studied for its optical properties. BSO exhibits strong photorefractive effects, making it useful for a range of applications, including holography, optical storage, and optical phase conjugation.
One of the advantages of BSO is its high diffraction efficiency, which makes it well-suited for holography applications. BSO also has a high sensitivity to green light, which allows it to be used in green-sensitive holographic materials.
In addition to its photorefractive properties, BSO has other optical properties that make it useful for certain applications. For example, BSO exhibits electro-optic properties, which make it useful in devices such as modulators and switches. BSO also has a high nonlinear coefficient, which makes it useful for frequency doubling applications.
Another advantage of BSO is its relatively low cost compared to other photorefractive crystals, such as lithium niobate or strontium barium niobate (SBN). This makes BSO an attractive option for researchers and engineers working on optical systems that require photorefractive effects.
