Record 1 2024-02-28

English

Subject field(s)
  • Lasers and Masers
CONT

In the field of laser-processing of materials, the extension in recent years to picosecond and subpicosecond lasers has brought attention to the important differences between conventional micromachining science, using nanosecond lasers, and new strong-field interactions driven exclusively by intense ultrafast laser pulses.

Key term(s)
  • sub-picosecond laser

French

Domaine(s)
  • Masers et lasers
CONT

Le rayonnement créé par interaction d'un laser subpicoseconde [...] avec une cible solide est apparu rapidement comme une source unique de photons X avec une durée de l'ordre d'une à dix picosecondes.

Key term(s)
  • laser sub-picoseconde

Record 2 2010-03-29

English

Subject field(s)
  • Electronic Circuits Technology
  • Photoelectricity and Electron Optics
CONT

Based on a micromachining process that can be adopted by current silicon production facilities, these are relatively inexpensive to manufacture and should allow the development of infrared imagers costing one or two orders of magnitude less than current designs, perhaps a few thousand dollars or less.

Key term(s)
  • micro-machining process
  • micro-machining

French

Domaine(s)
  • Technologie des circuits électroniques
  • Photo-électricité et optique électronique
DEF

Ensemble des techniques de microgravure isotropique ou anisotropique du silicium par attaque chimique, photolithographie, gravure par faisceaux d'ions, gravures «plasma».

CONT

La firme a mis au point des réseaux plan-focal bidimensionnels en silice micro-usinée, le micro-usinage est un nouveau procédé de fabrication en usage dans l'industrie microélectronique, sensibles à l'infrarouge.

OBS

micro-usinage : terme publié au Journal officiel de la République française le 27 décembre 2009.

Record 4 2002-08-16

English

Subject field(s)
  • Lasers and Masers
  • Machine-Tooling (Metallurgy)
CONT

Excimer lasers produce relatively wide beams of ultraviolet laser light. One interesting application of these lasers is their use in micromachining organic materials(plastics, polymers, etc). This is because the excimer laser doesn’t remove material by burning or vaporising it, unlike others types of laser, so the material adjacent to the area machined is not melted or distorted by heating effects.

French

Domaine(s)
  • Masers et lasers
  • Usinage (Métallurgie)
CONT

Dans un premier temps les prestations offertes [...] couvriront les domaines du micro-usinage par laser excimère ou femtoseconde et des mesures de surface (rugosité ou profilométrie optique). Il est prévu d'étendre cette action à d'autres lasers (CO2 ou YAG basse puissance) en conservant une spécificité de micro-usinage et traitements de surface.

Record 5 2001-08-22

English

Subject field(s)
  • Cutting and Trimming (Machine-Tooling)
CONT

Laser Micromachining in a Reactive Atmosphere. The drilling of deep holes in silicon by a laser beam is aided by conducting the operation in a reactive atmosphere. The atmosphere reacts with material ejected from the hole and converts the material to a gas that flows away from the work area. The hole is cleaner and more sharply defined, and debris do not spatter the surface of the work.

French

Domaine(s)
  • Découpage et taillage (Usinage)
CONT

Le micro-usinage laser met à profit les propriétés des impulsions les plus courtes. Une impulsion de 200 femtosecondes produit par ablation un trou parfaitement lisse dans l'acier.
