Over the past 20 years, we have witnessed spectacular advances in optical frequency comb technology that have revolutionized metrology and spectroscopy. Frequency combs have evolved from delicate setups confined to laboratories to compact field-deployable devices for real-life applications. Importantly, frequency combs continue to improve in terms of the output parameters and cost-effectiveness enabling ever growing number of applications. Recent breakthroughs include the first practical chip-scale combs, high power, ultra-low noise comb sources in the mid- and long-wave-IR and new classes of single-cavity dual-comb lasers, to name but a few.

In the first part of this topical review, the speakers from industry inform the audience about the innovative designs of optical frequency comb sources and new products based on those designs. The second part of the topical review features a variety of talks on the applications of optical frequency combs in spectroscopy, sensing and fundamental research.
