Frequency Combs

Vescent and the Danish National Metrology Institute (DFM) announce a highly accurate user-configurable optical clock assembled entirely from their commercially available components achieving 200 femtoseconds (0.0000000000002) timing instabilities at one second and sub nanosecond holdover at one day. Using Vescent’s commercially available, market-leading optical frequency comb (OFC), the FFC-100, to down-convert the clock cycle to the RF and the wavelength-stabilized output of the DFM Stabilaser 1542e as the clock laser, this powerful combination of components (including the Vescent SLICE-FPGA-II) yields a “Box to Clock” in less than 30 minutes (including warm-up time for all three devices), which customers can purchase today in North America for an introductory price of US$199,500 with a current lead-time of 6 to 12 weeks. Vescent is the exclusive Distributor for the DFM Stabilaser 1542e in the US and Canada.

Vescent and the Danish National Metrology Institute (DFM) have demonstrated hydrogen-maser-like performance of an acetylene optical clock assembled by simple integration of the two companies’ commercial-off-the-shelf (COTS) products. A 100 MHz clock output with frequency instability of 2.6x10^(-13)/√τ and a long-term instability reaching 8x10^(-15) around τ = 2,000 s was demonstrated by combining Vescent’s FFC-100 frequency comb with the DFM Stabilaser 1542ϵ optical frequency reference.

A rugged, compact, all-fiber frequency comb, designed and built to provide frequency stability transferable to the SWIR, NIR, visible, and RF spectra.

Fully stabilizable, with fractional Modified Allan Deviation below 10-22, the FFC-100 serves PNT, low-phase noise microwave, field sensing, and quantum security & computing applications in the lab and in the field.
