- Demonstration of on-sky calibration of astronomical spectra using a 25 GHz near-IR laser frequency combGabriel G Ycas
Department of Physics, University of Colorado, Boulder, CO, USA
Opt Express 20:6631-43. 2012..Stellar targets were observed in three echelle orders over four nights, and radial velocity precision of ∼10 m/s (∼6 MHz) was achieved from the comb-calibrated spectra...
- Generation of a 660-2100 nm laser frequency comb based on an erbium fiber laserGabriel Ycas
Department of Physics, University of Colorado, Boulder, Colorado, USA
Opt Lett 37:2199-201. 2012..Extension of the frequency comb into the visible is achieved by supercontinuum generation from the 1040 nm light. Comb coherence is verified with cascaded f-2f interferometry and comparison to a frequency stabilized laser...
