Abstract: A semiconductor laser arrangement and a projector are disclosed. In an embodiment the semiconductor laser arrangement includes at least two electrically pumped active zones, each active zone configured to emit laser radiation of a different emission wavelength and a semiconductor-based waveguide structure, wherein the active zones are electrically independently operable of one another, wherein the active zones optically follow directly one another along a beam direction and are arranged in a descending manner with regard to their emission wavelengths, wherein at least in a region of a last active zone along the beam direction, a laser radiation of all active zones jointly runs through the waveguide structure, wherein at least the last active zone comprises a plurality of waveguides which are stacked one above the other and are oriented parallel to one another, wherein one of the waveguides is configured for the radiation emitted by the last active zone.

Abstract: A method of autostereoscopic imaging including providing an autostereoscopic illumination unit including a lens field composed of a multiplicity of individual lenses or concave mirrors, and modulating an emission characteristic of the light source such that the individual lenses or the concave mirrors are illuminated only partly by the light source, wherein light from the light source impinges on the individual lenses or concave mirrors such that an emission characteristic of a three-dimensional object is imitated, the lens field extends over a spatial angle range of at least 2 sr relative to the light source or an external observer, the individual lenses or concave mirrors are distributed over the lens field and are at least partially sequentially irradiated, and the light source is formed by one or more lasers and the laser or each of the lasers irradiates/irradiate only one of the individual lenses at a specific point in time.
