The invention discloses a high power laser diode comprising a plurality of laser light emitters () and a plurality of light collimating means (), wherein each of the laser light emitters () defines, in a direction perpendicular to a direction of propagation () of an output laser beam, a fast axis (y) and a slow axis (x), and wherein each of the light collimating means is associated with a laser light emitter and configured for collimating the output laser beam at least in a fast axis (y) direction. In order to enable a simple and cost-efficient assembly of the diode laser with collimating means, having a layered structure consisting of a plurality of plane-parallel substrates. For this purpose, the diode laser comprises planar substrate means () which serves to precisely define a distance between a respective laser light emitter () and an associated light collimating means to the order of one or several millimetres and to support the collimating means () such that the optical axis of said laser light emitters are parallel to each other and for defining a precise location of emitters on the planar substrate (), preferably at predetermined distance in fast axis direction between said laser light emitters. The collimating means is an array or multiple single of micro-optical lenses having a rear side which is bonded to the upper surface of the planar spacer means. The submounts of the light emitters () are mounted to the planar substrate means () and to a heatsink ().

High power diode laser having multiple emitters and method for its production

An apparatus for shaping the output beam of a strip of lasers, or an array of such strips, comprising a first reflective member including at least a first reflective element for deflecting a first portion of the output beam in a first direction oriented at a first angle in the slow axis direction and at a second angle in the fast axis direction, and at least a second reflective member including at least a first reflective element for deflecting the first output beam portion from the first direction to a second direction in the Z axis. The output beam is thus shaped to define at least two beams comprising at least the first portion and a remainder of the output beam which is propagated along the Z axis without deflection by any reflective member, with the first portion of the output beam being oriented approximately parallel to the un-deflected remainder.

A method for three-dimensional display in which a plurality of individual image elements &#x3b1;are made visible simultaneously in a raster of columns i and lines j, wherein the image elements &#x3b1;reproduce partial information from a plurality of views A(k1 . . . n) of a scene/object, and adjacent image elements &#x3b1;radiate light of different wavelengths or wavelength regions is provided. In a method of the type described above, wavelength-dependent propagation directions are predetermined for the light radiated from the image elements &#x3b1;. The propagation directions within an observation space in which an observer is situated intersect in a plurality of intersection points which correspond to observation positions. From each observation position, one eye of an observer perceives predominantly partial information of a first selection and the other eye perceives predominantly partial information of a second selection from views A(k=1 . . . n).
