Abstract
A partially reflecting optical component ( ) generating, from an incident beam ( ), two secondary beams, one of them being reflected ( ), the other one being transmitted ( ). According to the invention, it comprises a first wholly reflecting planar face ( ) and a second partially reflecting planar face ( ), the second face being perpendicular to the first one, a third wholly reflecting planar face ( ), the first and third faces being in the same plane, this component providing the unidimensional auto-alignment of the reflected beam ( ) with the incident beam ( ), 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.
