Subharmonic Entrainment Breather Solitons in Ultrafast Lasers.

Physical Review Letters, 2020
We study theoretically and experimentally the subharmonic entrainment (SHE) breather soliton in mode-locked lasers for the first time, in which the ratio of the breather period to the round-trip time is an integer. We build a non-Hermitian degeneracy map

Revealing the Buildup Dynamics of Harmonic Mode‐Locking States in Ultrafast Lasers

Laser & Photonics reviews, 2019
Harmonic mode‐locking (HML) is an important technique enabling the generation of high‐repetition‐rate ultrashort pulses. Using an emerging time‐stretch dispersive Fourier transform technique, the experimental observation of the entire buildup process of ...

VSe2 nanosheets for ultrafast fiber lasers

, 2020
In this work, we investigate VSe2 for generating femtosecond and large energy mode-locked laser pulses for the first time. Two types of VSe2 based saturable absorbers (SAs), microfiber–VSe2 and VSe2/polyvinyl alcohol (PVA), are prepared, which exhibit ...

Ultrafast laser pulses

Physics Today, 1971
By “ultrafast” we mean those light pulses that last from about 10−13 seconds to a few tens of picoseconds. The anticipation of using them to study ultrafast processes in physics and chemistry has stimulated efforts to produce these pulses, and the results have been good; in 1962 the shortest pulse available was 10−8 sec, but by 1968, 10−13-sec pulses ...
