Title (EN) FLOW-TYPE GAS LASER
(FR) LASER A GAZ DU TYPE A ECOULEMENT
Abstract:
(EN) A laser comprises a sealed, gas-filled casing (1) on the opposite walls (1a, 1b) of which are mounted mirrors (2, 3) adjusted along the optical axis (O1-O1) of the laser resonance chamber (4) formed between the mirrors (2, 3). The casing (1) further houses a means for circulating the gas along a closed circuit through the laser resonance chamber (4) in a direction perpendicular to its optical axis (O1-O1), a means for generation of electric discharge in the laser resonance chamber (4) and a heat exchanger for gas cooling. The means for gas circulation and the heat exchanger for gas cooling constitute a single unit (5) comprising a hollow shaft (6) on which are coaxially mounted disks (7) with a gap between each other and whose cavity (8) is connected to a system for circulating the cooling agent through it.
(FR) Un laser comprend un boîtier étanche rempli de gaz (1), dont les parois opposées (1a, 1b) sont équipées de miroirs (2, 3) alignés le long de l'axe optique (O1-O1) dans la chambre à résonance laser (4) formée entre les miroirs (2, 3). Le boîtier (1) abrite également un moyen d'acheminement du gaz le long d'un circuit fermé à travers la chambre à résonance laser (4) dans une direction perpendiculaire à son axe optique (O1-O1), un moyen de génération d'une décharge électrique dans la chambre à résonance laser (4) et un échangeur de chaleur pour le refroidissement du gaz. Ledit moyen d'acheminement du gaz et l'échangeur de chaleur pour le refroidissement du gaz constituent un seul bloc (5), comportant un arbre creux (6) sur lequel sont montés de manière coaxiale des disques (7) mutuellement espacés, et dont la cavité (8) est reliée à un système permettant d'y introduire l'agent de refroidissement.
