Dual-comb spectroscopy (DCS) is a promising approach for real time, high precision, and
high sensitivity Fourier-transform spectroscopy. DCS requires a pair of tightly phase-locked …

Single-cavity, dual-comb lasers are those specially designed mode-locked lasers that can
emit more than one, asynchronous ultrashort pulse trains with stable repetition frequency …

Dual-comb spectroscopy holds the promise as real-time, high-resolution spectroscopy tools.
However, in its conventional schemes, the stringent requirement on the coherence between …

Fourier-transform spectroscopy is an indispensable tool for analyzing chemical samples in
scientific research as well as the chemical and pharmaceutical industries. Recently, its …

Mode-locked fiber lasers that can simultaneously generate two asynchronous ultrashort
pulse trains could play an attractive role as the alternative light sources for low-complexity …

We present a dual-comb spectrometer based on two passively mode-locked waveguide
lasers integrated in a single Er-doped ZBLAN chip. This original design yields two free …

Microwave photonic solutions of frequency measurement have advantages in broad
frequency coverage, but achieving high-resolution measurement remains a challenge …

By introducing an additional comb beyond its dual-comb predecessor, tri-comb consisting of
three combs with different mode spacing has shown its unique potential in several metrology …

We demonstrate a polarization-multiplexed, single-laser system for terahertz (THz) time-
domain spectroscopy without an external delay line. The fiber laser emits two pulse trains …

We report an all-fiber switchable dual-wavelength mode-locked laser using a Sagnac loop
mirror. In this laser, the Sagnac loop mirror acts as a tunable periodic filter, in which the …
