976 nm noise-like pulse mode-locked fiber laser
Shenzhen Daxue xuebao. Ligong ban, 2023 Pulse lasers with an output wavelength of 976 nm play an important role in scientific research and industrial fields. Using a nonlinear optical loop mirror (NOLM), we build a 976 nm mode-locked fiber laser with a figure-9 resonant cavity.

Symbiotic coexistence of noise-like pulses
Optics Express, 2021 Noise-like pulse (NLP) can split and then self-assemble into dynamic bound states, named NLP polymer. Here, we reported the first observation, to the best of our knowledge, of the buildup process of bound NLPs in all-normal-dispersion Yb-doped fiber lasers.

Chirped pulse Raman amplification in plasma: high gain measurements [PDF]
, 2009 High power short pulse lasers are usually based on chirped pulse amplification (CPA), where a frequency chirped and temporarily stretched ``seed'' pulse is amplified by a broad-bandwidth solid state medium, which is usually pumped by a monochromatic ...
