Calcium Thermal Beam Optical Clock

A simple, compact alternative to the highest performing optical standards, the Ca clock uses a thermal beam of neutral atoms with one or two lasers to achieve
Compact Cold Atom Clock

Compact Cold Atom Instruments

The cooling of atoms to microkelvin temperatures using lasers is currently enabling a new generation of precision instruments that take advantage of the long
Web interface to control and monitor the servo with interactive blocks

FPGA Design

Our group is developing FPGA based digital phase noise measurement and control systems.
CombSpec1

Frequency Comb Spectroscopy

We use frequency combs based on ultrafast mode-locked lasers to perform precision spectroscopy in the near- and mid-infrared domains, for rapid, high
