METHOD FOR ENGRAVING SOLID ARTICLES WITH LASER BEAMS AND THE ARTICLES PRODUCED

摘要

A method for engraving a series of consecutive cells in a solid surface, such as a liquid transfer surface, by impinging on the surface a pulsed laser beam in which the pulses of the laser beam are formed in a series of consecutive groups of two or more consecutive pulses and each of said groups form an individual-cell in the solid surface. The article produced is also described.
