Er-Doped Frequency Comb


Optical Frequency Synthesizer, Er-Doped

  • Fiber-Based Femtosecond Frequency COmb System
  • Patented Optical Frequency Comb Technology
  • Extension for Visible Spectral Range Available


  • Includes M-Comb Oscillator, Amplifier, and f:2f Interferometer
  • Extension Packages Available for the NIR or Visible Spectral Range

The FC1500 Optical Frequency Synthesizers are compact and flexible fiber-based femtosecond frequency comb systems. With an extension package for the visible spectral range, the system provides a stabilized optical frequency comb for frequency metrology in both the visible and the near infrared regions of the spectrum. A wide range of optional units enables us to tailor this versatile system to customer-specific metrology solutions.

The optical frequency comb technology and the stabilization of it are covered by several international patents (e.g., see EU patent EP 1161782 and US patent 6,785,303 B1). Menlo Systems holds the exclusive rights on the patents. The 2005 Nobel Prize in Physics was awarded to one of the founders of Menlo Systems, Theodor W. Hänsch, and J. Hall for their invention of the frequency comb technology.
