Abstract

The specification of the HIRES spectrograph proposed for the forthcoming Extremely Large Telescope (ELT) requires a traceable calibration source with gap-free coverage from 370-2500 nm, except for a region from 1350- 1440 nm aligned with atmospheric absorption [1]. In [2] we described a route to a broadband astrocomb from 0.5 to 2.2m based on a 1-GHz Ti:sapphire oscillator and a phase-coherent optical parametric oscillator (OPO). We now report the development of this work which has demonstrated a 10-GHz astrocomb extended from a degenerate optical parametric oscillator (OPO), producing a comb spanning 1.15-1.8m, with individual comb-mode positions identified. We show that the comb-mode positions obtained through Fourier-transform spectrometry can be fitted with sufficient accuracy to obtain the carrier envelope offset of the original OPO source comb.
