Abstract

Système de refroidissement (100) d'un milieu amplificateur laser (30), comprenant un circuit agencé en boucle fermée et configuré pour, en utilisation, recevoir un liquide caloporteur (20) en circulation. Le circuit comprend une cuve (160), pour recevoir le milieu amplificateur laser (30) immergé dans le liquide caloporteur (20), un réservoir amont (150), équipé d'une surverse amont (155) pour fixer l'altitude de la surface libre (S1) du liquide caloporteur (20) dans le réservoir amont, et un réservoir aval (170), équipé d'une surverse aval (175) pour fixer l'altitude de la surface libre (S2) du liquide caloporteur (20) dans le réservoir aval, avec les réservoirs amont et aval disposés de sorte qu'en utilisation, le liquide caloporteur traverse successivement le réservoir amont, la cuve et le réservoir aval. Selon l'invention, l'un au moins parmi le réservoir amont (150), le réservoir aval (170), une ouverture d'évacuation (157) de la surverse amont, et une ouverture d'évacuation (177) de la surverse aval, est monté réglable en altitude. On obtient ainsi un écoulement gravitaire de liquide caloporteur dans la cuve.
