World-leading optical frequency comb technology is now available in the midinfrared region. Taking advantage of Menlo Systems’ proprietary figure 9® modelocking technology, Menlo Systems’ difference frequency generation (DFG) based Mid-IR combs provide access to the 3-14 μm range. The reliable, turn-key mid-IR Comb is an enabling tool for applications in the important fingerprint region for high accuracy spectroscopy or nanoFTIR.


  • 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.
