Conference PaperDynamic Laser Frequency Combs for Astronomical Spectrograph Characterization and CalibrationSekhar, Pooja; Fredrick, Connor; Kreider, Molly Kate; Zhong, Peter; Mahadevan, Suvrath; Diddams, Scott A<p>We demonstrate a dynamic frequency comb, which is tunable in both frequency and intensity, to characterize and calibrate an astronomical spectrograph. These capabilities are critical for achieving cm/s level radial velocity precision to detect Earth-analogs.</p>Optica Publishing Group2025-01-0110656336SS123_2https://doi.org/10.1364/CLEO_SI.2025.SS123_22009982National Science Foundation
