DISPOSITIF DE GESTION DE FAISCEAU

摘要

The laser beam control is implemented by a moving arm with multiple articulated segments (1-8) carrying an optical unit to form an image of the laser output on the target surface. The articulated arm has mirrors at the junctions to transmit the laser beam inside the arm. The optical device at the free end of the arm incorporates a converging lens and a focus zoom. The arms carrying the laser beam may be evacuated or filled with an inert gas or with air, from which the dust has been removed. The laser emitters have Fourier or multi-mode transform cavities forming the uniform surface densities which are enlarged and delivered to the surface to be processed.
