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…
Broadband stability of the Habitable Zone Planet Finder Fabry-Pérot etalon calibration system: evidence for chromatic variation
Ryan C Terrien, Joe P Ninan, Scott A Diddams +11
The comb-like spectrum of a white light-illuminated Fabry-Pérot etalon can serve as a cost-effective and stable reference for precise Doppler measurements. Understanding the stabil…
Optical Frequency Comb Calibrated Near Infrared Solar Heterodyne Spectroscopy
Connor Fredrick, Freja Olsen, Ryan Terrien +3
We perform heterodyne spectroscopy at 1.56 micron with a tunable laser and thermal radiation from the Sun. The laser tuning is calibrated with a frequency comb, providing a simple…
Frequency stability of the mode spectrum of broad bandwidth Fabry-Perot interferometers
Jeff Jennings, Ryan Terrien, Connor Fredrick +5
When illuminated by a white light source, the discrete resonances of a Fabry-Perot interferometer (FP) provide a broad bandwidth, comb-like spectrum useful for frequency calibratio…
Impact of crosshatch patterns in H2RGs on high precision radial velocity measurements: Exploration of measurement and mitigation paths with HPF
Joe P. Ninan, Suvrath Mahadevan, Gudmundur Stefansson +9
Teledyne's H2RG detector images suffer from cross-hatch like patterns which arises from sub-pixel quantum efficiency (QE) variation. In this paper we present our measurements of th…
