Abstract
A device for emitting a light beam intended to form an image includes a plurality of sources, each emitting a beam of the laser type. The device is configured to form the light beam by combining the laser beams, and includes attenuation means, situated downstream of the plurality of sources, making it possible to vary the optical power of the light beam. The attenuation means includes one or more retractable filters, and is able to be interposed in the laser beams.
