Dynamic spectral tailoring of a 10 GHz laser frequency comb for enhanced calibration of astronomical spectrographs
Pooja Sekhar, Connor Fredrick, Peter Zhong +3
Laser frequency combs (LFCs) are an important component of Doppler radial velocity (RV) spectroscopy that pushes fractional precision to the level, as required to identi…
Frequency Comb Calibrated Laser Heterodyne Radiometry for Precision Radial Velocity Measurements
Ryan K. Cole, Connor Fredrick, Winter Parts +6
Disk-integrated observations of the Sun provide a unique vantage point to explore stellar activity and its effect on measured radial velocities. Here, we report a new approach for…
Tunable 30 GHz laser frequency comb for astronomical spectrograph characterization and calibration
Pooja Sekhar, Molly Kate Kreider, Connor Fredrick +5
The search for earth-like exoplanets with the Doppler radial velocity technique is an extremely challenging and multifaceted precision spectroscopy problem. Currently, one of the l…
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…
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…
Visible to Ultraviolet Frequency Comb Generation in Lithium Niobate Nanophotonic Waveguides
Tsung-Han Wu, Luis Ledezma, Connor Fredrick +6
The introduction of nonlinear nanophotonic devices to the field of optical frequency comb metrology has enabled new opportunities for low-power and chip-integrated clocks, high-pre…
