Title (EN) LASERS WITH SETBACK APERTURE
(FR) LASERS À OUVERTURE EN RETRAIT
Abstract:
(EN) The present disclosure relates, generally, to lasers and, more particularly, to lasers with a setback aperture. In one illustrative embodiment, a laser comprises front and rear resonator mirrors, an output window positioned near the front resonator mirror, and a plurality of waveguide walls extending between the front and rear resonator mirrors and extending between the rear resonator mirror and an aperture defined by the plurality of waveguide walls, such that a laser beam formed between the front and rear resonator mirrors will propagate in free-space between the aperture and the output window so that a first cross-sectional profile of the laser beam at the aperture will be different than a second cross-sectional profile of the laser beam at the output window.
(FR) La présente invention concerne, de manière générale, des lasers et, plus particulièrement, des lasers dotés d'une ouverture en retrait. Dans un mode de réalisation illustratif, un laser comprend des miroirs de résonateur avant et arrière, une fenêtre de sortie positionnée à proximité du miroir de résonateur avant, et une pluralité de parois de guide d'ondes s'étendant entre les miroirs de résonateur avant et arrière et s'étendant entre le miroir de résonateur arrière et une ouverture définie par la pluralité de parois de guide d'ondes, de sorte qu'un faisceau laser formé entre les miroirs de résonateur avant et arrière se propage dans l'espace libre entre l'ouverture et la fenêtre de sortie de sorte qu'un premier profil de section transversale du faisceau laser au niveau de l'ouverture soit différent d'un second profil de section transversale du faisceau laser au niveau de la fenêtre de sortie.
