    Abstract: The invention relates to a lighting apparatus (2) for providing light for processing an object (3). A ring of light sources generates processing light for processing the object and an imaging unit (9) images the ring of light sources onto a working plane (16) in which the object is to be processed, wherein the ring of light sources and the imaging unit are configured such that images of the light sources in the working plane are distributed equidistantly in a direction being parallel to a diameter of the imaged ring in the working plane. The ring arrangement allows for a high quality imaging with a relatively small and technically simple optical element. A relatively small lighting apparatus can therefore be provided, which can be used for applications like laser printing.

    Abstract: The invention relates to a lighting apparatus (1) comprising an array (2) of light sources (3) emitting emission cones (4) with edges (5) which intersect in an intersection plane and a lens unit (7) for homogenizing the intensity distribution in the far field. The array of the light sources and the lens unit are arranged such that i) the emission cones traverse the lens unit and ii) the distance (s) between the array of the light sources and the lens unit deviates from the sum of or the difference between a) the focal length f of the lens unit and b) the distance t between the intersection plane and the array (2) of the light sources (3) by 20 percent or less. This configuration leads to an intermixture of the emission cones in the far field such that the intensity distribution in the far field is substantially homogeneous.

    Abstract: The present invention relates to an optically pumped vertical external-cavity surface-emitting laser device comprising at least one VECSEL (200) and several pump laser diodes (300). The pump laser diodes (300) are arranged to optically pump the active region (108) of the VECSEL (200) by reflection of pump radiation (310) at a mirror element (400). The mirror element (400) is arranged on the optical axis (210) of the VECSEL (200) and is designed to concentrate the pump radiation (310) in the active region (108) and to form at the same time the external mirror of the VECSEL (200). The proposed device avoids time consuming adjustment of the pump lasers relative to the active region of the VECSEL and allows a very compact design of the laser device.

    Abstract: The invention relates to a lighting apparatus (10) for providing processing light for processing an object. Groups of light sources generate light for processing the object, wherein the groups of light sources are imaged onto a working plane (17) by an imaging unit (16) for producing the processing light. The resulting intensity distribution is configured such that, if the intensity distribution is integrated in a spatial integration direction, the resulting integrated intensity distribution has an intensity dip, wherein one or several of the groups of light sources are controllable independently from the other of the groups of light sources for modifying the integrated intensity distribution. This allows using the lighting apparatus in a processing apparatus such that perpendicular to a processing line, along which an object is to be processed, in particular, to be sealed, the object can be processed relatively homo genously, therey improving the quality of processing the object.
