Programs and Projects
Microresonator Device Research

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

Frequency Comb Spectroscopy

We use optical frequency combs to perform precision spectroscopy in the visible and, more recently, mid-infrared, domains, for rapid, high … more

Frequency Comb Calibration of Astronomical Spectrographs

We have constructed portable frequency combs that have provided in situ calibration of astronomical spectrographs, to aid in the search for … more

Optical Cavities for Laser Stabilization

Optical cavities are essential elements of optical atomic clocks, as they serve to pre-stabilize the clock laser. Our Group is currently … more

Optical and Microwave Waveform Synthesis

We use femtosecond-laser frequency combs to generate optical and microwave waveforms with unprecedented noise performance. more

Calcium Optical Beam 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 … more
