Dual-comb spectroscopy is an innovative optical technique that exploits pairs of laser frequency combs—light sources whose spectra consist of equidistant narrow lines—to facilitate high-resolution, ...

The ultrabroadband infrared frequency comb could be used for chemical detection in portable spectrometers or high-resolution remote sensors. (Nanowerk News) Optical frequency combs are specially ...

Laser spectroscopy is a powerful tool for atmospheric gas analysis, yet traditional methods face challenges due to atmospheric turbulence and significant energy loss. While dual-comb spectroscopy ...

Ultrabroadband IR frequency comb could be used for detection in portable spectrometers. The comb uses a double-chirped mirror. Researchers at MIT have demonstrated a compact, fully integrated ...
