How-to

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.

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.
