As a postdoc Diddams built the first optical frequency combs in the lab of Nobel laureate John Hall, and throughout his career, he has pioneered the use of these powerful tools for optical clocks, ...

The frequencies of these lines are known to a very high degree of accuracy, which makes frequency combs an important tool in optical metrology and high-resolution spectroscopy. Abhinand ...

The free-form dual-comb spectroscopy idea evolved from the optical frequency comb system. This laser-based platform “produces light at a series of equally spaced, precise frequencies that resemble the ...

The new approach, which also produces extremely accurate and stable frequencies, could enhance high-resolution atomic and molecular spectroscopy. Optical frequency combs — a type of laser that ...

Our work on mid-infrared OFC generation by synchronously pumped femtosecond OPOs is briefly described on the Frequency-comb spectroscopy page. Along with various difference-frequency generation ...

The physical interaction between two or more systems, also known as coupling, can give rise to unique and unexpected effects.

My main area of research relates to the development of laser and parametric optical frequency combs and their application to optical atomic clocks, tests of fundamental physics, trace gas sensing, ...

Vescent unveils RUBRIComb™: a rugged, ultra-stable optical frequency comb redefining reliability for atomic clocks & quantum computing systems.

Our research topics include Trace gas detection with photoacoustic and cavity-enhanced spectroscopy Optical frequency comb spectroscopy and infrared frequency comb generation using nonlinear optics ...

For the first time ever, scientists have used a technique called "quantum squeezing" to improve the gas sensing performance of devices known as optical frequency comb lasers. These ultra-precise ...

from timekeeping to molecular detection via spectroscopy. Yet because frequency combs require bulky, costly, and power-hungry equipment, their deployment has been largely limited to laboratory ...
