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 ...

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 ...

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 ...

Monochromators are an essential part of many spectrometers, important for a range of applications. This article describes what a monochromator is, how it works, the different types, what they are used ...

Proteins are naturally fluorescent in the ultraviolet, offering an appealing approach to probe proteins in their native state without introducing any external fluorescent label. The UV ...

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 ...
