Abstract

La présente invention concerne un système laser (100) qui sert à produire des impulsions laser de sortie (70), comprenant un laser SEED (10) destiné à produire une impulsion laser SEED (20) à partir de laquelle peut être produite une impulsion laser à injecter (48) qui: par l'intermédiaire d'un élément d'injection (68), peut être injectée dans un amplificateur à récupération qui présente un résonateur (50), un élément de couplage commandable (80) disposé dans celui-ci, et un disque à semi-conducteur (76) qui sert de support laser actif; et qui peut être amplifiée dans l'amplificateur à récupération en tant qu'impulsion laser amplifiée par plusieurs passages jusqu'à ce que l'impulsion laser amplifiée soit extraite de l'amplificateur à récupération sous la forme d'une impulsion de sortie (70). L'invention a pour objet d'apporter des améliorations au système laser de sorte que des impulsions laser de sortie à durées d'impulsions courtes peuvent être obtenues pour un coût minimal. A cet effet: dans le cadre de la production des impulsions laser de sortie, l'impulsion laser injectée (48) est produite dans un intervalle de temps inférieur à cinq picosecondes par rapport à l'impulsion laser SEED (20) sensiblement sans augmentation de durée d'impulsion liée à la dispersion positive; et la densité énergétique maximale par impulsion laser amplifiée dans le support laser actif (76) est inférieure à un joule par centimètre carré.
