The research of the Optical Metrology Group (OMG) centers on optical metrology and sensing, ultimately aiming to develop experiments sensitive enough to track time variations of fundamental constants. To that end, we are working on novel schemes in broadband precision spectroscopy and light-matter interaction of structured light. Our research includes work on low-noise (mid-IR) fiber lasers, mid-IR supermirrors, environmentally stable single-cavity dual-combs, and frequency combs in general.
