Description
Dual frequency comb systems offer unique capabilities for spectroscopy, hyperspectral imaging, and ultrafast photonics, combining high temporal and spectral resolution with rapid electronic measurements. Despite their potential, challenges in simultaneously achieving broad spectral bandwidth, low noise, and high power have limited their applications. In this work we overcome these issues and introduce the first shot-noise limited, coherently averaged dual-comb interferometry from a supercontinuum source, featuring 450 nm bandwidth, gigahertz pulse repetition rate, and output power exceeding 1 W. Both combs are generated in a compact setup using a single free-running solid-state laser cavity and a single polarization-multiplexed photonic crystal fiber, making the system well-suited for field applications.
