Welcome to the Frequency Combs & Quantum Metrology Group!

Ìý

This is the web home of the research group of Prof. Scott Diddams. We seekÌýto develop optical measurement tools that lead to new physicalÌýunderstanding and enable technological and scientificÌýbreakthroughs.Ìý A central theme is the development andÌýuse ofÌýoptical frequency combsÌýfor quantum metrology.ÌýThis includes topics in laser science and engineering,Ìýprecision timing, optical clocks, astronomy, ultrafast lasersÌýand nonlinear optics, nonlinear nano-photonics, microwaveÌýphotonics, and spectroscopy from the UV to THz.Ìý
