Using two optical frequency combs and a photon counter, the experiments open up exciting prospects for conducting dual-comb spectroscopy in low-light conditions and they pave the way for novel ...

High-frequency light is useful. The higher the frequency of light, the shorter its wavelength—and the shorter the wavelength, the smaller the objects and details the light can be used to see. Extreme ...

An ultraviolet photon-counting dual-comb spectrometer. Two ultraviolet frequency combs of slightly different pulse repetition frequencies are generated at very low light levels by nonlinear frequency ...

A kilogram of iron sulfate costs pennies. A kilogram of platinum costs tens of thousands of dollars. Both metals can help ...

This is an artist's conception of JILA's extreme ultraviolet (EUV) frequency comb. The original light source is a pulsed infrared laser, which is used to create a train of attosecond-long pulse bursts ...

(Nanowerk News) In a recent publication in Nature ("Near-ultraviolet photon-counting dual-comb spectroscopy"), researchers at the Max Born Institute (MBI) in Berlin, Germany, and at Max-Planck ...

High-frequency light is useful. The higher the frequency of light, the shorter its wavelength – and the shorter the wavelength, the smaller the objects and details the light can be used to see. So ...
