Abstract

Selon l'invention, un système laser comprend une source de pompage qui produit une première sortie. La source de pompage possède un boucle de rétroaction avec une première jonction de sommation et une première commande à point de quantification d'échelon ou de réglage numérisé. Un dispositif de sortie est couplé à la source de pompage afin de recevoir la première sortie et de produire une seconde sortie. Une boucle de rétroaction est couplée à la première jonction de sommation. La boucle de rétroaction comprend une seconde jonction de sommation couplée à au moins une partie de la seconde sortie. La seconde jonction de sommation reçoit une seconde commande et délivre une entrée à la première jonction de sommation. La boucle de rétroaction réduit la quantification d'échelon à partir de la première sortie afin de délivrer un échelon de commande plus fine d'une propriété de la seconde sortie.
