Single-cavity dual-comb lasers are a new type of ultrafast lasers with wide application potential. The researchers propose a method for multiplexing a single laser cavity to support noise-correlated modes, achieving high-energy, short-pulse, and low-timing-noise laser output.
Single-cavity dual-comb lasers are a new class of ultrafast lasers that have a wide possible application space including pump-probe sampling, optical ranging, and gas absorption spectroscopy. However, to date, laser cavity multiplexing has usually come with a trade-off in laser performance or relative timing noise suppression. We present a method for multiplexing a single laser cavity to support a pair of noise-correlated modes. These modes share all intracavity components and take a near-common path, but do not overlap on any active elements. We implement the method with an 80-MHz laser delivering more than 2.4 W of average power per comb with sub-140-fs pulses. We reach sub-cycle relative timing jitter of 2.2 fs [20 Hz, 100 kHz]. With this multiplexing technique, we can implement slow feedback on the repetition rate difference 1 frep, enabling this quantity to be drift-free, have low jitter, and be adjustable-a key combination for practical applications that was lacking in prior single-cavity dual-comb systems.
