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 ...

Their report, published in Advanced Photonics, describes an approach called spatial-resolved asynchronous-sampling terahertz spectroscopy (SPRATS), which combines the best features of two distinct ...

(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) ...

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 ...

Spectroscopists are often required to identify an unknown compound from a measured spectrum, verifying sample integrity, and defining detected impurities in a sample. Performing a spectral search can ...
