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 …

Time has always had a special status in physics because of its fundamental role in
specifying the regularities of nature and because of the extraordinary precision with which it …

A coherent optical frequency comb is a kind of broad-spectrum light sources delivering
equidistant frequencies, and correspondingly its temporal waveform appears as a sequence …

The broadband, coherent nature of narrow-linewidth fiber frequency combs is exploited to
measure the full complex spectrum of a molecular gas through multiheterodyne …

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 …

In this paper, a review of fiber laser technology as relevant for applications in ultrafast optics
is given. We discuss core enabling fiber technologies, such as fiber amplifiers, all-fiber …

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