Record 1 2000-04-25

English

Subject field(s)
  • Welding - Various Processes
CONT

Precise YAG welding and optimum design for optics.

PHR

Long wave pulse YAG welding system; high power Nd YAG welding laser.

French

Domaine(s)
  • Procédés de soudage divers
CONT

On utilise actuellement deux grandes classes de machines selon l'application visée, qui dépendent du type de laser utilisé : les machines YAG et les machines CO2. Soudage YAG. [Les] lasers YAG [...] sont des lasers solides dont le milieu, de nature cristalline, est un grenat d'aluminium-yttrium [...] Le cristal, transparent, se présente sous la forme d'un barreau cylindrique. Cette configuration, imposée par son élaboration, gouverne toute la technologie du laser et ses performances, dont la puissance maximale (il existe aujourd'hui des cristaux YAG dits slab, ou plaques, plus performants thermiquement et plus puissants). Il impose une cavité stable mono- ou multimodule pour laquelle il n'y a pratiquement pas de variantes.

Record 2 1989-03-23

English

Subject field(s)
  • Lasers and Masers
DEF

A laser in which the frequency of the output radiation can be tuned over part or all of the ultraviolet, visible, and infrared regions of the spectrum

CONT

Use of tunable lasers. The sharpness of the frequency and the high power per unit solid angle and unit spectral bandpass in a laser beam make it attractive for infrared spectroscopy at ultrahigh resolution. The main problem is the tuning of the laser frequency, that is, varying some parameter in the laser system so that its frequency may be varied continuously and accurately.

French

Domaine(s)
  • Masers et lasers
DEF

laser à longueur d'onde réglable.

CONT

Le développement récent des lasers accordables (dont on peut régler la fréquence d'émission) ouvre les perspectives d'une photochimie sélective par laser permettant une meilleure compréhension des mécanismes des réactions chimiques.
