SEVILLE, Spain, Nov. 7, 2024 —Innovators in the global timing community are interested in advanced clocks with femtosecond short-term timing stability and improved long-term stability over GPS, where consistent operation doesn't require user intervention.

Vescent is stepping up to the challenge. Their optical clock kit with commercial-off-the-shelf (COTS) components can be tailored to specific customer needs for application validation.

At the November 2024 International Timing and Sync Forum (ITSF) , Vescent Director of R&D Kevin Knabe showcased that such a kit can exhibit long-term femtosecond stability with better-than-GPS long-term stability (currently at the one-day timescale, but long-term measurements are being investigated further).

This technology would advance and protect vulnerable GPS-reliant systems, influencing fields such as stock trading, power transmission, navigation, information transfer, image analysis, and more.

Dr. Knabe shared test results showing low frequency instability on the microwave output and also presented a range of operational environmental testing, including operation from 0 - 50⁰C as well as in the presence of vibrations above 1.5 gRMS (well above that observed in typical server rooms and government transportation specifications).

Vescent hardware can survive non-operation environments roughly 10 times harsher than the operational environments. Vescent continues to innovate in the optical clock and quantum sensor space by increasing the ruggedness and reducing the size, weight, and power (SWaP) of frequency-controlled laser sources while offering the lowest price for such systems on the market.
