Abstract

La présente invention concerne un convertisseur de luminosité à deux étages. Un premier étage de conversion de luminosité comporte une cavité laser comportant un premier guide d'ondes optique dopé avec un ion actif définissant une première bande optique avec absorption optique, une deuxième bande optique avec absorption optique et gain optique et une troisième bande optique avec gain optique. La première cavité laser est pompée avec une puissance de pompage ayant une longueur d'onde dans la première bande optique pour générer un signal optique intermédiaire dans la deuxième bande optique. Un second étage de conversion de luminosité qui est en cascade avec le premier étage de conversion de luminosité comprend un second guide d'ondes optique dopé avec le même ion actif. Le second étage de conversion de luminosité est pompé avec le signal optique intermédiaire pour obtenir un signal optique à forte luminosité dans la troisième bande optique.
