| 英文摘要 | 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. |
