Dual-comb spectroscopy is an innovative optical technique that exploits pairs of laser frequency combs—light sources whose spectra consist of equidistant narrow lines—to facilitate high-resolution, ...

How it works: the top frequency comb is passed through a sample of interest and then into a beamsplitter. The bottom frequency comb operates at a slightly different pulse repetition frequency and is ...

(Nanowerk News) In a recent publication in Nature ("Near-ultraviolet photon-counting dual-comb spectroscopy"), researchers at the Max Born Institute (MBI) in Berlin, Germany, and at Max-Planck ...

Researchers at the Max Planck Institute of Quantum Optics (MPQ) have successfully developed a new technique for deciphering the properties of light and matter that can simultaneously detect and ...

…and Stanford launches “micro” frequency comb, as basis for mass-market adoption of such devices. An ultraviolet photon-counting dual-comb spectrometer. Scientists in the group of Nathalie Picqué at ...

Dual-comb spectroscopy (DCS) has rapidly become a cornerstone of precision molecular detection, offering unparalleled resolution, broad spectral coverage, and fast acquisition speed. From fundamental ...

Physicists achieve major leap in precision and accuracy at extremely low light levels. Researchers at the Max Planck Institute of Quantum Optics (MPQ) have successfully developed a new technique for ...

Huang (left) and a graduate student discuss a project in their lab. It is sometimes said that science is about truth, while engineering is about compromise. With one laser project in his lab in the ...

The ability to describe the internal structure of atoms is important not only for understanding the composition of matter, but also for designing new experiments to explore fundamental physics.
