First doppler-free signal!

Late friday nights in the lab seem to yield the most results. Here is an oscilloscope trace of our first Doppler free saturated absorption spectroscopy signal. The broad peak is absorption due to all the lithium atoms (with a spread in velocities), while the narrow peaks are due only to atoms at rest along the direction of the laser beam.

Bon Voyage, Tabi!

Tabi is leaving to spend some time in the UK, followed by a semester abroad. On her last day in the lab this year, we sealed up the spectroscopy vacuum chamber and pumped it down to just below $$10^{-4}$$ Pa. Great work, and see you in 2020!

First Labsnacks Box!

Our first order from Thorlabs arrived today. My initial excitement was dampened by the confusion of all the students: "Is this... American food?".

Summer research begins

A warm welcome to the newest members of the lab: Tabitha, Rishav, and Devendra! This summer, they'll build some of the foundations of the lab infrastructure: lab monitoring sensors, experimental control software, and a vacuum chamber for saturated absorption spectroscopy.
