2.4 µm Dual-Comb Spectroscopy

Not Accessible

Your library or personal account may give you access

Abstract

A proof-of-principle experiment of mid-infrared frequency comb Fourier transform spectroscopy is carried out with two interfering Cr2+:ZnSe femtosecond oscillators, emitting around 2400 nm. Spectra of acetylene are measured within 10 µs with 12 GHz resolution.
