We review the most recent progress in ultralow-noise mode-locked fiber lasers and fiber-
based frequency-comb sources. With the rapid progress in theory, measurement, and …

We describe the design, fabrication, and performance of a self-referenced, optically coherent
frequency comb. The system robustness is derived from a combination of an optics package …

Two coherent frequency combs are used to measure the full complex response of a sample
in a configuration analogous to a dispersive Fourier transform spectrometer, infrared time …

We discuss experimental and theoretical aspects of a low-noise fiber-laser frequency comb,
including the experimental configuration and the major contributions to the frequency noise …

We demonstrate a self-referenced fiber frequency comb that can operate outside the well-
controlled optical laboratory. The frequency comb has residual optical linewidths of< 1 Hz …

We present a flexible all-polarization-maintaining (PM) mode-locked ytterbium (Yb): fiber
laser based on a nonlinear amplifying loop mirror (NALM). In addition to providing detailed …

We demonstrate that fiber-based frequency combs with multi-branch configurations can
transfer both linewidth and frequency stability to another wavelength at the millihertz level …

Optical frequency combs have revolutionized optical frequency metrology and are being
actively investigated in a number of applications outside of pure optical frequency metrology …

Femtosecond frequency combs are among the most precise measurement tools in
existence. They have applications ranging from high‐precision spectroscopy and metrology …

When a photo-diode is illuminated by a pulse train from a femtosecond laser, it generates
microwaves components at the harmonics of the repetition rate within its bandwidth. The …
