Broadband dual-comb hyperspectral imaging and adaptable spectroscopy with programmable frequency combs
Fabrizio R. Giorgetta, Jean-Daniel Deschênes, Richard L. Lieber +3
We explore the advantages of a free-form dual-comb spectroscopy (DCS) platform based on time-programmable frequency combs for real-time, penalty-free apodized scanning. In traditio…
Open-path Dual-comb Spectroscopy for Multispecies Trace Gas Detection in the 4.5 μm to 5 μm Spectral Region
Fabrizio R. Giorgetta, Jeff Peischl, Daniel I. Herman +4
Open-path dual-comb spectroscopy provides multi-species atmospheric gas concentration measurements with high precision. Here, we extend open-path dual comb spectroscopy to the mid-…
Dual-comb spectroscopy with tailored spectral broadening in SiN nanophotonics
Esther Baumann, Eli V. Hoenig, Edgar F. Perez +10
SiN waveguides, pumped at 1550 nm, can provide spectrally smooth, broadband light for gas spectroscopy in the important 2 m to 2.5 m atmospheric wat…
Continuous regional trace gas source attribution using a field-deployed dual frequency comb spectrometer
Sean Coburn, Caroline B. Alden, Robert Wright +9
Identification and quantification of trace gas sources is a major challenge for understanding and regulating air quality and greenhouse gas emissions. Current approaches either pro…
High Coherence Mid-Infrared Dual Comb Spectroscopy Spanning 2.6 to 5.2 microns
Gabriel Ycas, Fabrizio R. Giorgetta, Esther Baumann +4
Mid-infrared dual-comb spectroscopy has the potential to supplant conventional high-resolution Fourier transform spectroscopy in applications that require high resolution, accuracy…
Accurate frequency referencing for fieldable dual-comb spectroscopy
Gar-Wing Truong, Eleanor M. Waxman, Kevin C. Cossel +6
A fieldable dual-comb spectrometer is described based on a "bootstrapped" frequency referencing scheme in which short-term optical phase coherence between combs is attained by refe…
Synchronization of Distant Optical Clocks at the Femtosecond Level
Jean-Daniel Deschenes, Laura C. Sinclair, Fabrizio R. Giorgetta +6
The use of optical clocks/oscillators in future ultra-precise navigation, gravitational sensing, coherent arrays, and relativity experiments will require time comparison and synchr…
Mid-Infrared Optical Frequency Combs based on Difference Frequency Generation for Molecular Spectroscopy
Flavio C. Cruz, Daniel L. Maser, Todd Johnson +5
Mid-infrared femtosecond optical frequency combs were produced by difference frequency generation of the spectral components of a near-infrared comb in a 3-mm-long MgO:PPLN crystal…
Open-Air, Broad-Bandwidth Trace-Gas Sensing with a Mid-Infrared Optical Frequency Comb
Lora Nugent-Glandorf, Fabrizio Giorgetta, Scott A. Diddams
A mid-Infrared frequency comb is produced via an optical parametric oscillator (OPO) pumped by an amplified 100 MHz Yb:fiber mode-locked laser. We use this source to make measureme…
Frequency Comb-Based Remote Sensing of Greenhouse Gases over Kilometer Air Paths
Gregory B. Rieker, Fabrizio R. Giorgetta, William C. Swann +10
We demonstrate coherent dual frequency-comb spectroscopy for detecting variations in greenhouse gases. High signal-to-noise spectra are acquired spanning 5990 to 6260 cm^-1 (1600 t…
Optical two-way time and frequency transfer over free space
Fabrizio R. Giorgetta, William C. Swann, Laura C. Sinclair +3
The transfer of high-quality time-frequency signals between remote locations underpins a broad range of applications including precision navigation and timing, the new field of clo…
