Dual-comb correlation spectroscopy of thermal light
Eugene J. Tsao, Alexander J. Lind, Connor Fredrick +8
The detection of light of thermal origin is the principal means by which humanity has learned about our world and the cosmos. In optical astronomy, in particular, direct detection…
Temperature, Pressure, Velocity, and Water Vapor Mole Fraction Profiles in a Ramjet Combustor using Dual Frequency Comb Spectroscopy and a High Temperature Absorption Database
David Yun, Scott C. Egbert, Nathan A. Malarich +9
Accurate diagnostics of the combustor region of ramjet engines can improve engine design and create benchmarks for computational fluid dynamics models. Previous works demonstrate t…
Precision Doppler Shift Measurements with a Frequency Comb Calibrated Laser Heterodyne Radiometer
Ryan K. Cole, Connor Fredrick, Newton H. Nguyen +1
We report precision atmospheric spectroscopy of using a laser heterodyne radiometer (LHR) calibrated with an optical frequency comb. Using the comb-calibrated LHR, we record…
Supersonic Combustion Diagnostics with Dual Comb Spectroscopy

11-μs Time-resolved, Continuous Dual-Comb Spectroscopy with Spectrally Filtered Mode-locked Frequency Combs
Nazanin Hoghooghi, Ryan K. Cole, Gregory B. Rieker
Broadband dual-comb spectroscopy (DCS) based on portable mode-locked fiber frequency combs is a powerful tool for in situ, calibration free, multi-species spectroscopy. While the a…
The Gemini/HST Galaxy Cluster Project: Environment Effects on the Stellar Populations in the Lynx Clusters at z=1.27
Inger Jorgensen, Laura C. Hunter, Conor R. O'Neill +4
Few detailed investigations of stellar populations in passive galaxies beyond z~1 are based on deep spectroscopic observations, due to the difficulty in obtaining such data. We pre…
Baseline-free Quantitative Absorption Spectroscopy Based on Cepstral Analysis
Ryan K. Cole, Amanda S. Makowiecki, Nazanin Hoghooghi +1
The accuracy of quantitative absorption spectroscopy depends on correctly distinguishing molecular absorption signatures in a measured transmission spectrum from the varying intens…
Broadband Dual Frequency Comb Spectroscopy in a Rapid Compression Machine
