Off-Axis Parabolic Mirrors

World-leading optical frequency comb technology is now available in the mid-infrared 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.

Analysis of the out of loop beat signal between two ULNplus combs at the Strontium clock transition frequency: The extremely low phase noise proves that the spectral purity is transfered to the target wavelength, which makes the ULNplus a unique clockwork for Strontium and other optical lattice clocks.
