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
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

Yb Lattice Clock

Our Group is developing high stability, high accuracy optical atomic clocks based on thousands of Yb atoms confined to an optical lattice. Such clocks will find
Microcombs2

Microresonator Device Research

With micro-resonators (fabricated in house or by collaborators) we are developing microcombs, integrated reference cavities and low-noise laser sources. The
