Abstract
We present recent advances in astrocomb technology for precision calibration of astronomical spectrographs. We detail first results from a compact high-resolution Fourier-transform spectrometer (FTS) for comb-line identification; we discuss progress in high-repetition-rate solid state lasers which will remove the need for Fabry-Pérot cavities (FPCs); and we describe recent work towards achieving full spectral coverage from 0.4–2.4 μm from a single comb source. Finally, we present results from the calibration of HRS at SALT using a partially-stabilized frequency comb.
