Review of low timing jitter mode-locked fiber lasers and applications in dual-comb absolute distance measurement

Nanotechnology and Precision Engineering, 2018
Passively mode-locked fiber lasers emit femtosecond pulse trains with excellent short-term stability. The quantum-limited timing jitter of a free running femtosecond erbium-doped fiber laser working at room temperature is considerably below one ...

Defect‐Templated Phase Engineering in Atomically Thin Metals

Advanced Materials, EarlyView.
Graphene defects are transformed from passive imperfections into programmable templates for phase‐selective growth of atomically thin silver. Plasma‐generated boundary defects favor Ag(1), whereas sp3‐rich zero‐layer graphene promotes Ag(2). This defect‐directed intercalation links local graphene chemistry to crystalline phase, electronic structure ...

Lasers for ultrafast laser-materials processing

, 2022
S.37-98Nearly all advances made in processing materials in the fs (< 100 fs) domain have so far been achieved with the use of Ti:Sapphire lasers at a wavelength of 800 nm. For longer pulses (< 1 ps), lasers operating at 1 µm have played an important role.
