Abstract

Le problème à résoudre dans le cadre de la présente invention consiste à proposer un oscillateur laser à répétition élevée, à impulsion stable, qui emploie un milieu laser ayant un gain d'amplification faible, tel qu'une forme plane mince. Comme solution, on propose un solide oscillateur laser qui comprend au moins une paire de résonateurs laser, un mince milieu laser plan auquel une substance active ayant une durée de vie de niveau supérieur plus longue que la période de l'opération de répétition à mesure qu'un support laser est ajouté, un mince milieu laser plan disposé sur au moins un réflecteur dans le résonateur laser et un élément de commutation Q disposé dans le résonateur, une source de pompage pour pomper le milieu laser de façon optique, et une section de commande pour commander l'élément de commutation Q. La section de commande démarre l'oscillation avec l'élément de commutation Q à l'état actif et commute le commutateur Q à l'état inactif pendant l'oscillation, ce qui permet à la densité de niveau supérieur de la substance active dans le milieu laser de se maintenir, interrompant ainsi l'oscillation. Puisque la densité de pompage de niveau supérieur est maintenue de telle sorte qu'une impulsion de commutateur Q peut être amenée à osciller lorsque le commutateur Q est activé, une oscillation d'impulsion à répétition élevée stable peut être obtenue.
