Optical frequency combs were developed nearly two decades ago to support the world's
most precise atomic clocks. Acting as precision optical synthesizers, frequency combs …

Since the discovery of electron-wave duality, electron scattering instrumentation has
developed into a powerful array of techniques for revealing the atomic structure of matter …

As the only method for all-weather, all-time and long-distance target detection and
recognition, radar has been intensively studied since it was invented, and is considered as …

Locking of longitudinal modes in laser cavities is the common path to generate ultrashort
pulses. In traditional multi-wavelength mode-locked lasers, the group velocities rely on …

Optical atomic clocks represent the state of the art in the frontier of modern measurement
science. In this article a detailed review on the development of optical atomic clocks that are …

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 …

The ability to generate lower-noise microwaves has greatly advanced high-speed, high-
precision scientific and engineering fields. Microcombs have high potential for generating …

Edited by internationally recognized authorities in the field, this expanded and updated new
edition of the bestselling Handbook, containing many new articles, is aimed at the design …

The ability to process optical signals without passing into the electrical domain has always
attracted the attention of the research community. Processing photons by photons unfolds …

The time-of-flight of light pulses has long been used as a direct measure of distance,, but
state-of-the-art measurement precision using conventional light pulses or microwaves peaks …
