Beat note detection at 895 nm with an EOT detector
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.
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.

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
