Bismuth Silicate (BSO) Single Crystal Substrates

Description

Bismuth Silicate (Bi₁₂SiO₂₀, BSO) single crystal substrates are highly versatile electro-optic and photorefractive materials with cubic symmetry. They feature high photoconductivity, significant electro-optic coefficients, and excellent photorefractive properties, making them ideal for applications such as holography, dynamic optical data storage, four-wave mixing, and real-time image processing. Their stable physical properties and broad transparency range also make them attractive for optoelectronic and laser-related research.

Key Features and Properties:

• High Electro-optic and Photorefractive Properties: Suitable for real-time holography and optical data processing.
• Cubic Crystal Structure: Isotropic optical properties, facilitating easier device integration.
• High Photoconductivity: Enhances photorefractive response and device efficiency.
• Broad Transparency Range: From ~450 nm to 7000 nm.
• High Optical Damage Threshold: Suitable for high-intensity light exposure.
• Excellent Thermal and Chemical Stability: Reliable under varied operating conditions.

Typical Applications:

• Dynamic holography and real-time holographic displays
• Optical phase conjugation and four-wave mixing
• Optical data storage and retrieval
• Beam coupling and photorefractive two-wave mixing
• Optical computing and image processing
• Research in nonlinear optics and optoelectronic devices
