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 ...

Using nonlinear crystals to convert the frequency of a laser gets a new look as an Italian researcher unveils a 3/2 frequency multiplier that could simplify RGB laser systems. Multiplying the ...

(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) ...

A recent article published in the journal Nature Communications demonstrates time-resolved fluorescence spectroscopy using entangled photon pairs from a continuous-wave laser, replacing ultrafast ...

Raman spectroscopy is an analytical technique that allows for the assessment of molecular structure and the identification of materials by examining the rotational and vibrational modes of molecules.
