Abstract
A partially reflecting optical component (11) generating, from an incident beam (12), two secondary beams, one of them being reflected (13), the other one being transmitted (14). According to the invention, it comprises a first wholly reflecting planar face (15) and a second partially reflecting planar face (16), the second face being perpendicular to the first one, a third wholly reflecting planar face (17), the first and third faces being in the same plane, this component providing the unidimensional auto-alignment of the reflected beam (13) with the incident beam (12), the respectively transmitted and reflected beams being each formed with two half-beams having matching wave fronts. The invention also relates to an external cavity laser source comprising such a component as a unidimensional auto-aligned reflector.
