Abstract

L'invention concerne une source de signaux pourvue d'un dispositif du type résonateur Raman en cascade doté d'un signal de germes servant à réguler la sortie spectrale de la source. Plusieurs instructions de Stokes sont produites dans un milieu à gain, l'instruction de Stokes la plus élevée étant autorisée à sortir. Le signal de germes est fourni au milieu à gain par une source de germes, et se situe dans la gamme de longueur d'onde de l'instruction de Stokes la plus élevée. Le signal de germes stimule le gain décalé Raman dans la gamme de longueur d'onde dudit signal, ce qui permet de réguler la gamme de longueur d'onde de sortie du milieu à gain. Dans un mode de réalisation, le signal de germes est un signal à bande large qui produit une sortie à bande large à partir du milieu à gain. Dans un autre mode de réalisation, le signal de germes est produit par un certain nombre de sources à bande étroite couplées avant introduction au milieu à gain. La source de germes peut être réglée de façon à ajuster la distribution spectrale énergétique de la sortie à partir de la source de signaux. L'ajustement peut se faire en combinaison avec la surveillance active des signaux de la sortie de la source de signaux. On peut également utiliser la source de signaux pour pomper un milieu à gain dans lequel un signal voulu est amplifié, la distribution spectrale énergétique de ce signal pouvant être surveillée aux fins des ajustements de la source de germes.
