Abstract:
An external cavity laser source including an optical component forming a unidimensional auto-aligned reflecting system and allowing extraction of an outgoing flow from the source, the optical component generating, from an incident beam, two secondary beams, one of the secondary beams being reflected, the other secondary beam being transmitted, said optical component comprising:a first completely reflecting planar face; a second partially reflecting planar face, perpendicular to the first face; a third completely reflecting planar face; the first and third faces being disposed in the same plane, said component providing unidimensional auto-alignment of said one of the secondary beams with the incident beam, the one and the other of said secondary beams being each formed with two half-beams having matching wave fronts, and within the cavity, a diffraction network arranged in a Littman-Metcalf configuration, with respect to the optical component.
