Abstract

L'invention concerne un dispositif de commande de la durée d'impulsion et/ou de l'énergie d'impulsion d'une impulsion laser dans un laser à modulation passive de qualité, ou du taux de répétition du laser en fonctionnement continu, caractérisé par une commande destinée au réglage mécanique du système de modulation de qualité. L'invention concerne également un dispositif de commande de la durée d'impulsion et/ou de l'énergie d'impulsion d'une impulsion laser dans un laser à modulation passive de qualité avec allongement du résonateur par fibres optiques, ou du taux de répétition des impulsions individuelles du laser en fonctionnement continu, caractérisé en ce que la commande est effectuée par réglage mécanique du système résonateur. Ainsi, il est possible de mettre en oeuvre des lasers dont la puissance émise en temps est variable.
