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 ... -
Mid-IR frequency comb source spanning 4.4-5.4 mu m based on subharmonic GaAs optical parametric oscillator
Vodopyanov, KL; Sorokin, E; Sorokina, Irina T; Schunemann, PG (Journal article, 2011)Broadband mid-IR output suitable for producing 1000-nm-wide frequency combs centered at 4.9 μm was achieved in a degenerate subharmonic optical parametric oscillator (OPO) based on 500-μm-long Brewster-angled orientation-patterned ... -
Sensitive multiplex spectroscopy in molecular fingerprint 2.4 um region with a Cr2+:ZnSe femtosecond laser
Sorokin, E; Sorokina, Irina T; Mandon, J; Guelachvili, G; Picque, N. (Journal article; Peer reviewed, 2007)An ultrashort-pulse Cr2+:ZnSe laser is a novel broadband source for sensitive high resolution molecular spectroscopy. A 130-fs pulse allows covering of up to 380 cm-1 spectral domain around 2.4 µm which is analyzed ... -
Spatial-temporal structure of the femtosecond third harmonic generation in photonic-crystal fibers
Kalashnikov, VL; Sorokin, E; Sorokina, Irina T (Journal article; Peer reviewed, 2007)We analyze the third harmonic generation by the supercontinuum at 1.5 µm in nonlinear-glass microstructured fibers. The numerical model includes the real field dynamics and allows analyzing the spectral as well as the ... -
Watt-level Kerr-Lens Mode-Locked Cr:ZnS Laser at 2.4 μm
Tolstik, Nikolai; Sorokin, E; Sorokina, Irina T (Chapter, 2013)Power scaling of Kerr-lens mode-locked Cr:ZnS femtosecond oscillator allows reaching 1 W output power and pulse energies over 8 nJ. Soliton and chirped-pulse regimes result in 68 fs and 0.8-2 ps pulses, respectively.
