*inquire about different wavelength ranges


Frequency comb technology makes direct measurement of absolute optical frequencies possible. With the Mid-IR Comb system we have extended the wavelength coverage into the Mid-IR spectral region. The mode frequencies are completely defined by the repetition rate only, as the carrier envelope offset frequency vanishes in a difference frequency generation process. Such, the turn-key Mid-IR Comb is the perfect tool for high accuracy spectroscopy in the fingerprint region of many molecules.


  • 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.

  • WLM-NIR Integrated Wavelength Meter

    Product Code: WLM-NIR

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

  • Tablemounted SmartComb Extensions

    Product Code: Tablemounted Extension

    The SmartComb can provide stabilized comb output as a seed, thereby extending the range from 530 to 2000 nm with optional retrofittable extensions.
