As laser measurement, optical sensing, and photonic research systems continue advancing toward higher precision and faster signal processing, optical frequency control has become essential for accurate measurement and signal manipulation. Acousto-optic frequency shifters (AOFS) are designed to precisely shift the frequency of incident laser beams, enabling advanced optical modulation and frequency conversion in demanding photonic applications.

• Precise Frequency Shifting:Supports optical frequency conversion from 20–300 MHz, with customizable center frequencies and shift values.
• Bidirectional Frequency Control:Depending on the incident angle, the output beam can be shifted upward or downward by the applied RF frequency.
• Cascaded Operation:Multiple AOFS units can be combined to achieve sum-frequency or difference-frequency configurations.
• High-Quality TeO? Crystal:Manufactured using in-house grown and polished Tellurium Oxide (TeO?) crystals for low insertion loss and high optical quality.
• Free-Space and Fiber-Coupled Versions:Available in both free-space and fiber-coupled configurations for flexible system integration.
• Wide Wavelength Coverage:Supports wavelengths from 355 nm to 1550 nm, covering UV, visible, and near-infrared laser systems.
• Matched RF Driver Solutions:Compatible RF driver modules are available for simplified implementation and system optimization.
