Device for treating the free surface of the material making up an object by laser irradiation

摘要

This is a device for treating the free surface of material by laser irradiation. The device includes power laser emission means (2) delivering substantially parallel laser beams (3) directed towards the surface of the material. The laser emission means (2) are arranged in a network representing the surface of the material to be treated. Means (4) provide for the control and modulation of the power of the radiation of each laser beam as a function of the absorption parameters and of the thickness of the zones of impact on the surface of the material. Application to the drying of patterns with a distinctive or ornamental character on a fixed or moving backing. <IMAGE>
