A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2022.210023 considers sub-femtometer-resolution absolute spectroscopy based on dual electro-optic frequency comb. Optical frequency ...
An atom is about 10^-10 m in size. The next smallest thing in nature is the nucleus, which is about 100,000 times smaller, i.e., 10^-15 m in size — a femtometer, or “fermi.” A nucleus is composed of ...
Be forewarned, you may spend way too much time at the Universcale website.In case you were wondering: A femtometer is one quadrillionth of a meter, a million times smaller than nanometer. In ...
(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) ...
