Abstract

L'invention concerne les circuits de refroidissement des lasers. Elle se rapporte à un laser dans lequel le bâtonnet 18 de matière active est refroidi par un circuit séparé de circulation d'un fluide de refroidissement alors que la chaleur dégagée par la lampe à éclairs 10 est extraite par une poudre 26 d'une matière céramique tassée entre la lampe à éclairs et la surface de la cavité de pompage optique, la chaleur étant transmise à un radiateur 13a qui la dissipe. La poudre peut être formée par exemple de sulfate de baryum. Application à la réalisation de lasers à solide peu encombrants.
