CA 2166471

A laser device incorporates a rectangular multi-mode beamsplitter waveguide (20) connected at one end to a retro-reflecting mirror (26). The beamsplitter waveguide (20) is connected at a second end to an output coupling waveguide (22) and a reflection coupling waveguide (24). The reflection coupling waveguide (24) is terminated by a second retro-reflecting mirror (27). Radiation produced within the device is reflected by me mirror (26) and coupled to the two coupling waveguides in a manner such that a partially reflecting mirror is not required at an output to the device.

Un dispositif laser comprend un guide d'ondes (20) diviseur de faisceaux multimode, rectangulaire, raccordé au niveau d'une extrémité à un miroir rétroréfléchissant (26). Le guide d'ondes diviseur de faisceaux (20) est raccordé au niveau d'une seconde extrémité à un guide d'ondes de couplage de sortie (22) et à un guide d'ondes de couplage à réflexion (24). Le guide d'ondes de couplage à réflexion (24) est terminé par un second miroir rétroréfléchissant (27). Le rayonnement produit dans le dispositif est réfléchi par le miroir (26) et couplé aux deux guides d'ondes de couplage, de manière à ce qu'il ne soit pas nécessaire de placer un miroir partiellement réfléchissant à une sortie du dispositif.
