CA 2420299

A solid-state apparatus for tracking the wavelength of a laser emission has a power splitter that divides the laser emission into at least three equal components. Differing phase shifts are detected and processed to track variations of the laser emission.

Un appareil à l'état solide qui effectue le suivi de la longueur d'ondes d'une émission laser comporte un diviseur de puissance qui divise l'émission laser en au moins trois composantes égales. Différents décalages en phase sont détectés et traités de manière à effectuer le suivi des variations de l'émission laser.
