Abstract
Laser diode apparatus, comprising a carrier () having a carrier top (), a laser diode chip () arranged on the carrier top () emitting, during operation, electromagnetic radiation through a radiating face (), which radiating face () runs perpendicularly to the carrier top (), and at least one optical element () to deflect at least some of the electromagnetic radiation radiated by the laser diode chip () perpendicularly to the carrier top (). By the use of a plurality of laser diode chips having wavelengths that differ very slightly from one another, speckles can be reduced. By means of a retarder plate () between the laser diode chip and the optical element it is possible to influence the polarization. A polarization cube enables the deflected light beam bundles to fully cover one another as differently polarized light beam bundles.
