2.4 μm dual-comb spectroscopy
Bernhardt, B; Sorokin, Evgeni; Jacquet, P; Thon, R; Becker, T; Sorokina, Irina T; Hansch, TW; Picque, Nathalie (Chapter, 2010)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 ... -
Mid-infrared dual-comb spectroscopy with 2.4 mu m Cr2+:ZnSe femtosecond lasers
Bernhardt, B; Sorokin, E; Jacquet, P; Thon, R; Becker, T; Sorokina, Irina T; Picque, N; Hansch, TW (Journal article, 2010)The mid-infrared part of the electromagnetic spectrum is the so-called molecular fingerprint region because gases have tell-tale absorption features associated with molecular rovibrations. This region can be for instance ...
