High-resolution electro-optically sampled broadband dual-comb spectroscopy across mid-IR to terahertz at video rate
Dmitrii Konnov, Andrey Muraviev, Sergey Vasilyev +1
Ultrabroadband electro-optic sampling with few-cycle optical pulses is known to be an extremely sensitive technique to detect electric field amplitudes. By combining this method wi…
Video-rate broadband longwave IR dual-comb spectroscopy with 240,000 comb-mode resolved data points
Sergey Vasilyev, Andrey Muraviev, Dmitrii Konnov +5
We report molecular detection using dual frequency-comb spectroscopy with highly coherent broadband (6.6-11.4 {\m}m) long-wavelength infrared (LWIR) combs. The combs were produced…
High-order (N=4-6) multi-photon absorption and mid-infrared Kerr nonlinearity in GaP, ZnSe, GaSe, and ZGP crystals
Taiki Kawamori, Peter G. Schunemann, Vitaly Gruzdev +1
We report a study of high-order multi-photon absorption, nonlinear refraction, and their anisotropy in four notable mid-infrared \c{hi}(2) crystals: GaP, ZnSe, GaSe and ZGP using t…
Two-octave-wide (3-12 μm) mid-infrared frequency comb produced as an optical subharmonic in a nondispersive cavity
Q. Ru, T. Kawamori, P. G. Schunemann +3
Coherent laser beams in the 3 to 20 μm region of the spectrum are most applicable for chemical sensing by addressing the strongest vibrational absorption resonances of the media. B…
Massively parallel dual-comb molecular detection with subharmonic optical parametric oscillators
Viktor O. Smolski, Honglei Yang, Jia Xu +1
Mid-infrared (mid-IR) spectroscopy offers unparalleled sensitivity for the detection of trace gases, solids and liquids, which is based on the existence of strong telltale vibratio…
Intracavity trace molecular detection with a broadband mid-IR frequency comb source
Magnus W. Haakestad, Tobias P. Lamour, Nick Leindecker +2
Ultrasensitive detection of methane, isotopic carbon dioxide, carbon monoxide, formaldehyde, acetylene and ethylene is performed in the spectral range 2.5 - 5 μm using intracavity…
Mid-infrared supercontinuum generation in tapered chalcogenide fiber for producing octave-spanning frequency comb around 3 μm
Alireza Marandi, Charles W. Rudy, Victor G. Plotnichenko +3
We demonstrate mid-infrared (mid-IR) supercontinuum generation (SCG) with instantaneous bandwidth from 2.2 to 5 μm at 40 dB below the peak, covering the wavelength range desirable…
All-Optical Quantum Random Bit Generation from Intrinsically Binary Phase of Parametric Oscillators
Alireza Marandi, Nick C. Leindecker, Konstantin L. Vodopyanov +1
True random number generators (RNGs) are desirable for applications ranging from cryptogra- phy to computer simulations. Quantum phenomena prove to be attractive for physical RNGs…
Sub-wavelength surface IR imaging of soft-condensed matter
James H. Rice, Graeme A. Hill, Stephen R. Meech +3
Outlined here is a technique for sub-wavelength infrared surface imaging performed using a phase matched optical parametric oscillator laser and an atomic force microscope as the d…
