Various aspects are analyzed, which are related to the generation of unusual laser pulses
with stochastic internal structure known as noise-like pulses. A new mechanism of their …

Harmonic mode‐locking (HML) is an important technique enabling the generation of high‐
repetition‐rate ultrashort pulses. Using an emerging time‐stretch dispersive Fourier …

Topological insulators (TIs) exhibit exciting optical properties, which open up a new pathway
to generate ultrashort pulses from fiber lasers. Layered TIs display distinct saturable …

Some background as well as recent progress in the development of femtosecond lasers are
discussed together with a brief outline of a few representative emergent applications in …

We experimentally demonstrate the use of a bulk-like, MoSe_2-based saturable absorber
(SA) as a passive harmonic mode-locker for the production of femtosecond pulses from a …

Passive harmonic-mode locking of erbium-doped fiber laser with atomic multilayer graphene
is presented. The laser could operate at several harmonics (from 2nd to 21st) of the …

In this letter we present for the first time, to the best of our knowledge, a harmonically mode-
locked Er-doped fiber laser with antimony telluride (Sb 2 Te 3) topological insulator material …

We present a kind of harmonic mode locking of bound-state solitons in a fiber laser based
on molybdenum disulfide (MoS_2) saturable absorber (SA). The mode locker is fabricated …

We demonstrate a passive harmonically mode-locked erbium-doped fiber laser that
operates at selectable harmonics spanning from the 6th to the 928th, which corresponds to …

Frequency combs with mode spacing of 10–20 GHz are critical for increasingly important
applications such as astronomical spectrograph calibration, high-speed dual-comb …
