Abstract

Un laser à cavité repliée à compensation d'astigmatisme (10) produit une sortie à modes verrouillés. A cet effet, on place dans la cavité, séparé du milieu actif (14), un élément lentille (28), non linéaire et produisant un effet de lentille dépendant de l'intensité. Des miroirs à l'intérieur de la cavité (24, 26) focalisent la radiation laser sur l'élément (28), et une ouverture ou fente (22) à l'intérieur de la cavité est située au niveau d'une partie resserrée du faisceau pour permettre l'utilisation d'une cavité alignée.
