Experiment Control

Some work requires two lasers to be locked with larger offset frequencies. In

this application note we demonstrate a method for achieving offsets of at least 43 GHz with indications that with the proper equipment the offset could be extended to 100 GHz or more.

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.

Shankar Menon of the University of Chicago won a qNimble Quarto!
