Frequency comb technology makes direct measurement of absolute optical frequencies possible. The FC1000 Optical Frequency Synthesizer is a compact, portable and flexible fiber-based femtosecond frequency comb system. The system is capable of providing at the same time a source for frequency metrology in both the visible and the near-IR regions (520-1040 nm) of the spectrum. A wide range of optional units enables us to tailor this versatile system to customer specific metrology solutions.


  • EOM-Phase EOM-Phase Electro-optic Phase Modulator

    Product Code: EOM-Phase

    Integrated into the laser cavity; allows high-performance phase locking to an optical reference by increasing the bandwidth of the repetition rate lock by more than an order of magnitude. With this EOM option sub-Hz line widths can be achieved. Required for high-performance phase locking to an optical reference.

  • FPC1000 Fabry Perot Cavity for Mode Filtering

    Product Code: FPC1000

    Increases the fundamental mode spacing to a user-defined frequency in the 2 to 25 GHz range. The Fabry-Perot is actively temperature stabilized and both input and output are fiber coupled.

  • M-520 High Power Measuring Port around 520 nm

    Product Code: M-520

    Output provides stabilized comb light with highest power at 520 nm. Contains an amplifier and subsequent frequency conversion, delivering minimum of 250 mW average power in a 3 nm window with a central wavalength at 520 nm.The output is free space.

  • BDU M-NIR Extension Package to the Near Inrfared Spectral Range

    Product Code: BDU

    Generates and measures the beat signal between the frequency comb and an external continuous wave (cw) laser. Available for various spectral ranges, with free space or fiber-coupled optics, and matched to the customer's laser.

  • Microwave M-NIR Extension Package to the Near Inrfared Spectral Range

    Product Code: Microwave

    Ultrastable RF output in the 1 MHz-10 GHz range. Utilizing a high-sensitive fast photodetector and a frequency divider where needed.

  • GPS M-NIR Extension Package to the Near Inrfared Spectral Range

    Product Code: GPS

    Provides the RF reference input signal for the frequency comb, combining the superior short term stability of an ultrastable quartz oscillator with the long term accuracy of the GPS.

  • WLM-NIR Wavelength Meter

    Product Code: WLM-NIR

    Integrated wavelength meter with 100 MHz accuracy at 900 - 1700 nm

  • WLM-VIS Wavelength Meter

    Product Code: WLM-VIS

    Integrated wavelength meter with 100 MHz accuracy at 500 - 1100 nm

  • SmartAmp SmartComb Extension

    Product Code: SmartAmp

    The SmartComb can be extended with a 19”, 3 HE rack containing up to 6 amplifiers, 6 beat detection units (BDU) and frequency counters. Using the SmartComb as a seed, the comb light is distributed and amplified with the SmartAmp. Together with internal BDUs and counters the system automatically measures your laser frequencies, in the range of 530-2000 nm, to the 14th digit. In addition, the beat signals serve as error signals to stabilize your CW laser (e.g. with a MenloSystems SYNCRO LLE unit) when required.

    In short: Stabilize all frequencies and transitions in your quantum optics laboratory to one absolute frequency reference!
