System of marking points with a laser.

摘要

System of marking points with a laser. This has the means for producing a plurality of beams and the means for reducing the space between the beams; it is characterized by including at least one laser 1 with several resonators that generate different beams. It has an electronic control unit 7 equipped with a means of entering and storing characters to be printed, a means of processing this information and a means for exciting the resonators. The means for reducing the space between the beams has a means of optical concentration 2. It includes a means of selecting the size of the character to print 6 which can be controlled automatically by means of a motor 5 controlled by the control 7. In addition, it has a focusing unit 4 which controls the energy of each of the beams with a working focal distance.
