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, ...

An ultraviolet photon-counting dual-comb spectrometer. Two ultraviolet frequency combs of slightly different pulse repetition frequencies are generated at very low light levels by nonlinear frequency ...

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 ...

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 ...

(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 ...

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 ...

(Nanowerk News) Optical frequency comb (OFC) provides equidistant comb lines in broad bandwidth, and each comb line corresponds to an absolute optical frequency, which is similar as a comb (or rule) ...

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 ...

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 ...
