APPARATUS FOR GENERATING A ROTATING LASER BEAM

摘要

The present invention relates to an apparatus (1) for generating a rotating laser beam (5) which may used for various applications including welding, cutting, drilling or ablation of materials. More particularly, the apparatus (1) according to the present invention is able to produce a fast rotating and accurate laser beam, because the main optical device (100) that is rotated consists of a first reflecting surface (102) rotating about an axis (X1), a second reflecting surface (26) having an annular shape, wherein the first reflecting surface (102) redirects said laser beam in to the direction of the second reflecting surface (26), which reflects said laser beam towards said axis (X1).
