Acousto-Optic Frequency Shifters (AOFS)

• Precise Frequency Conversion Capabilities

  • Shifts input laser light frequency up or down based on the applied RF signal frequency.
  • Cascadable design allows sum and difference frequency combinations for versatile applications.

• Premium Materials & Performance

  • Utilizes high-quality Tellurium Oxide (TeO2) with superior optical and acoustic properties.
  • TeO2 crystals are grown and polished in-house at CASTECH for low insertion losses and high damage thresholds.

• Wide Range of Frequency Shifts

  • Standard products offer frequency shifts from 20 MHz to 300 MHz.
  • Many devices are realized using bicrystal designs for added precision and efficiency.

• Fully Customizable to Your Needs

  • Customers can request custom specifications, including center frequency and shifted frequency values.
  • Compatible RF inverter driver solutions from Foxchip are available for matching AOFS needs.

Applications

• Interferometry – Accurate measurement tools for optical systems.
• Laser Cooling – Advanced manipulation of atomic systems using frequency shifts.
• Laser Doppler Velocimetry – For precise motion analysis and flow detection.
• Optical Heterodyne Detection – Essential in precision spectroscopy and detection systems.
