In 2007 Heriot-Watt was the first group worldwide to achieve carrier-envelope-offset locking of a femtosecond optical parametric oscillator (OPO), and subsequently reported a nearly 3-octave spanning comb from a synchronously-pumped Ti:sapphire-pumped OPO . Since then we have developed our capabilities, demonstrating Ti:sapphire, Yb:fibre and OPO frequency combs at repetition rates up to 1 GHz and spanning 400 — 4000 nm wavelength.

This talk will introduce the techniques behind frequency combs, explaining the principles of carrier-envelope offset locking, particularly in an OPO context. I will then discuss a number of applications of OPO combs, including dual-comb spectroscopy, precision optical metrology and coherent pulse synthesis with ~100-attosecond timing control. The talk will conclude by discussing some future opportunities for OPO frequency combs.
