English

Subject field(s)
  • Lasers and Masers
CONT

The ultrashort pulse laser is a generic name for any type of laser that produces pulses or bursts of coherent light in extremely short periods of time, usually measured in picoseconds or femtoseconds.

French

Domaine(s)
  • Masers et lasers
CONT

Ils suggéraient donc que l'utilisation d’un laser à impulsions ultracourtes, tel qu'un laser femtoseconde, pourrait permettre de réduire considérablement ces effets indésirables tout en rendant la procédure plus sûre et plus efficace.

DEF

A temporary increase in spectral transmittance of a filter caused by a high-pulse-power laser beam ...

OBS

Examples of high-pulse-power laser beam: a picosecond or femtosecond laser beam.

OBS

The process is reversible; the low-level transmission is not affected.

OBS

This process is also called the "Q-switch effect."

OBS

induced transmission: term and definition standardized by the International Organization for Standardization (ISO).

Domaine(s)
  • Mesures et analyse (Sciences)
  • Verres d'optique
  • Rayonnements électromagnétiques
  • Oeil
DEF

Augmentation temporaire du facteur de transmission spectrale d’un filtre provoquée par un faisceau laser à forte puissance d’impulsion [...]

OBS

Exemples de faisceaux laser à forte puissance d’impulsion : un faisceau laser picoseconde ou un faisceau laser femtoseconde.

OBS

Le processus est réversible; la transmission à faible niveau n’est pas affectée.

OBS

Ce phénomène est également désigné par l’expression «effet Q-switch».

OBS

transmission induite : terme et définition normalisés par l’Organisation internationale de normalisation (ISO).

Record 3 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.
