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 generation of sub‐optical‐cycle, carrier–envelope phase‐stable light pulses is one of
the frontiers of ultrafast optics. The two key ingredients for sub‐cycle pulse generation are …

The state of the art of ultrafast Er: fiber technology is reviewed. Such lasers are increasingly
used for generation of ultrabroadband and widely tunable pulse trains. Er: fiber sources …

We study the optical response of a resonant medium possessing nonlinear coupling to an
external field driven by a few-cycle pump pulse sequence. We demonstrate the possibility of …

The dissipative soliton regime is one of the most advanced ways to generate high-energy
femtosecond pulses in mode-locked lasers. On the other hand, the stimulated Raman …

The rapid development of the optical-cycle-level ultra-fast laser technologies may break
through the bottleneck of the traditional ultra-intense laser [ie, Petawatt (PW, 1015 W) laser …

The advancement of the ultrafast pulse sha** and waveform synthesis allowed to
coherently control the atomic and electronic motions in matter. The temporal resolution of the …

Timing jitter is one of the most important properties of femtosecond mode-locked lasers and
optical frequency combs. Accurate measurement of timing jitter power spectral density (PSD) …

After five decades of development, mode-locked lasers have become significant building
blocks for many optical systems in scientific research, industry, and biomedicine. Advances …

Optical frequency combs based on erbium-doped fiber lasers are attractive tools in precision
metrology due to their inherent compactness and stability. Here we study a femtosecond Er …
