Abstract

L'invention concerne un procédé pour stabiliser la puissance de départ d'un laser à corps solide à multiplication de fréquence à l'intérieur du résonateur. Selon ce procédé, au moins deux éléments du rayonnement émis par le laser à corps solide sont mesurés et servent à régler la puissance de départ du laser sur une valeur constante d'au moins une grandeur de réglage. Afin d'obtenir une très bonne stabilisation, une deuxième grandeur de réglage au moins entre en ligne de compte pour le réglage de la puissance de départ du laser. A cet effet, le système de laser à corps solide comporte un pompage à deux diodes lasers orientées de telle sorte que leurs sens de polarisation diffèrent.
