MARKING APPARATUS FOR MARKING AN OBJECT WITH LASER LIGHT AND MARKING SYSTEM COMPRISING SAID APPARATUS

摘要

The invention relates to a marking apparatus (100) for marking an object with laser light, comprising a plurality of gas lasers (10) and a control unit for individually activating each of the gas lasers (10) to emit a laser beam according to a sign to be marked. The gas lasers (10) are stacked such that the laser beams (90a-90i) emitted by the gas lasers form an array of laser beams, in particular a linear array with parallel laser beams. Each gas laser (10a-10i) comprises laser (resonator) tubes (12) that at least partially surround an inner area (5) of the apparatus (100), which further comprises beam-delivery means (14) for directing the laser beams (90a-90i) into the inner area (5) and a set of deflection means (30) for rearranging the array of laser beams into a desired array of laser beams. The set of deflection means (30) is arranged in the inner area (5) and comprises at least one deflection means (33a-33i, 34a-34i) per laser beam, in particular at least one mapping mirror (33a-33i, 34a-34i) or one optical waveguide per laser beam (90a-90i), each deflection means (33a-33i, 34a-34i) is individually adjustable in its deflection direction and/or individually shiftable.
