Stimulated Raman scattering, observed first in 1962, has become a versatile tool in diverse fields such as biological imaging, environmental gas sensing, materials characterization, and molecular ...

To address the current limitations of time-gated Raman spectroscopy, specifically its narrow spectral range and low spectral resolution, and simultaneously acquire Raman and fluorescence life-time ...

Quantum systems composed of solid-state electronic spins can be sensitive detectors of narrowband magnetic fields. A prominent example is the nitrogen-vacancy (NV) center in diamond, which has been ...

(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) ...

This study demonstrates a compact optical modulation platform that enables real-time, high-resolution spectroscopy using sub-MHz interleaved combs generated via chip-scale acousto-optic phase ...

Raman spectroscopy offers a powerful approach to chemical measurement. By directly probing molecular vibrations, it obtains chemical specificity without the need for chemical labels. Thanks to these ...

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 ...

Researchers have developed a new smaller, lighter design for space-based imaging spectrometers with high spectral resolution. These high-dispersion imaging spectrometers could be used onboard ...
