Direct optical Frequency Comb Spectroscopy (DFCS) is proving to be a fundamental tool in many areas of science and technology thanks to its unique performance in terms of ultra-broadband, high-speed ...

Absolute distance measurement techniques based on optical frequency combs have emerged as the gold standard for high-precision ranging over distances from micrometres to several kilometres. Optical ...

(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) ...

Researchers developed a frequency-comb-referenced terahertz Fabry-Pérot interferometry platform that measures lithium-ion ...

Menlo's optical frequency combs are a core component of optical clocks, such as this one at JILA. (Courtesy: GE Marti/JILA) This year marks the 20th anniversary of the first time an optical-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 ...
