Abstract:
A laser module is described for an image projection system, which has a duochromatic laser diode designed to generate a first beam bundle having laser light of a first wavelength and laser light of a second wavelength; a first collimating optics system designed to collimate the first beam bundle; at least one first monochromatic laser diode designed to generate a second beam bundle having laser light of a third wavelength; a second collimating optics system designed to collimate the second beam bundle; and a first optical combination device developed to combine the first and second beam bundles in order to form an output beam bundle of the laser module.
