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.
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).
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
