We theoretically investigate the generation of ultrafast currents in insulators induced by strong few-cycle laser pulses. Ab initio simulations based on time-dependent density functional theory give insight into the atomic-scale properties of the induced

A photocurable latex system enables high‐resolution vat photopolymerization of water‐dispersed thermoplastics, yielding pseudothermoplastic materials with recyclability. The formulation permits precise control over mechanical properties and supports reprocessing through conventional and extrusion‐based methods. Compatibility with two‐photon 3D printing

Cataract surgery with femtosecond lasers
Cataract surgery with femtosecond lasers is approaching its practical application in ophthalmology. These lasers, working in the near infrared wavelength (1030 nm) can penetrate the transparent and even opaque tissues of the anterior segment of the eye, with limitations related to vessels and mineral opacities.

Fabrication of in situ polymer‐encapsulated stable perovskite patterns of arbitrary shapes and pixel arrays with a resolution of 80 nm is reported by the femtosecond (fs) laser (800 nm) super‐resolution writing technique. The two‐photon absorption‐induced laser ablation is attributed to the achieved feature sizes as small as λ/10.

femtosecond laser ablation [PDF]
Femtosecond laser ablation was investigated as a solid sampling method for elemental chemical analysis. In comparison to the sampling with longer laser pulses, two aspects could be improved by using ultrashort pulses: elimination of the elemental fractionation from the ablation crater, which is necessary for an accurate quantitative analysis, and ...

This study evaluates the scalability of PQD GNC‐based LSCs for BIPV applications. Experimental data and Monte Carlo simulations predict performance up to 1 m2, achieving a peak power conversion efficiency of 3.17%. The results confirm the viability of these LSCs for energy‐efficient building applications.

A scalable method for direct laser patterning of 2D films on transparent substrates like polycarbonate and glass is presented. This technique eliminates the need for photolithography and solvents, enabling the fabrication of functional devices like strain gauges, supercapacitors, and photodetector arrays.

Materials processing with tightly focused femtosecond vortex laser beams
This letter is the first demonstration of material modification using tightly focused femtosecond laser vortex beams. Double-charge femtosecond vortices were synthesized with the polarization-singularity beam converter described in Ref [1] and then ...
