Integrated f(CEO) Phase Noise of 280 mrad RMS in a SESAM-based Frequency Comb Supporting a Fractional Frequency Instability of 1.3x10^(-17) at 1 s

Transferring the Long-Term Stability of a GPS-Disciplined OCXO to Vescent’s FFC-100 Optical Frequency Comb by Repetition Rate Locking

Vescent is a Tier 1 supplier for the Quantum ecosystem, enabling Quantum Computing, Networking, Timing, and Sensing. Our ambition is to move high-performance lasers from the lab into the field. Achieving low-noise laser operation in the presence of large environmental perturbations is our specialty.

The 1 GHz rep rate of a MENHIR-1550 was stabilized.

Nathan Lemke and his students at the Bethel University AMO lab locked a laser to a two-photon transition of rubidium-85. They used the qNimble Quarto as a modulation source, lock-in amplifier, and PI loop filter servo to effect a Pound Drever Hall (PDH) type lock.

Vescent has been awarded a $1.25M Direct-to-Phase II Small Business Innovation Research (SBIR) grant from the Air Force (AFRL, WPAFB) to develop a fully stabilized, multi-gigahertz-repetition rate optical frequency comb (OFC). 

Scott Davis, Vescent CEO will be a panelist on Quantum Computing at the Inside Quantum Technology Meeting in San Diego on Tuesday 10 May, 2022 at 10:45 am PDT.

We demonstrate a lock of a RIO PLANEX 1550nm narrow linewidth laser to the Vescent FFC-100 Fiber Frequency Comb using the Vescent D2-135 Offset Phase Lock Servo.

ColdQuanta, the quantum atomics company, has been selected by the Defense Advanced Research Projects Agency (DARPA) to develop a scalable, cold-atom-based quantum computing hardware and software platform that can demonstrate quantum advantage on real-world problems. The award is valued at up to $7.4M. Congratulations to our friends at ColdQuanta! Read the full press release here.

Q: What is the phase-noise on my laser beat-note going to look like when locked with the D2-135 Offset Phase Lock Servo (OPLS)? A: There are a lot factors that affect the final lock performance of the D2-135. Like frequency noise, phase noise is measured in terms of a noise density — or noise within
