Fiber-Coupled Laser Frequency Shifter

Generate cavity-stabilized light at any frequency with this fiber-coupled device.  We use acousto-optic modulation to rapidly shift light without frequent optical realignment. Tunes continuously over ±750 MHz to span the entire 1.5 GHz free spectral range of a standard stable reference cavity.

  • Available at any wavelength that our cavities are sold
  • Broad frequency shifting without optical realignment
  • Integrated software control can be programmed for cavity drift compensation

FPGA Laser Frequency Offset Unit

Traditional PDH cavity locking restricts the frequency of the stabilized laser to the cavity resonances at multiples of the cavity free spectral range. Tuning the stabilized laser frequency in between the resonances (with your atom or ion or to an offset w/ a second beam) often requires additional, expensive, power-hungry frequency shifters. This FPGA-based locking system fixes this problem without the need for these optical components, enabling you to lock your laser at any frequency and steer the locked laser output frequency with analog voltage inputs or digital commands.

  • High-speed synthesizer allows for offset frequencies from 15 MHz to 1.5 GHz, which can span most cavity FSRs.
  • A versatile, low-latency system, featuring cancellation of linear drift of your output light and auto-locking and re-locking technology.
  • Digital status messages and serial interface allow for easy integration into your experimental setup.
  • Available with a touch-screen interface.
