PROCEDURE FOR THE GENERATION OF A BRAND WITHIN A GLASS BODY.

摘要

Procedure for generating a mark that is below the surface in a glass body, which has a transmission curve with a horizontal section for wavelengths greater than those of X-rays, in which a ray of Laser type is directed to a surface of the body and this laser beam allows to cross the body to a certain depth previously specified for the mark and at the same time it is concentrated in a place previously specified for the mark inside the glass, as well as it presents in the mentioned place a power density that generates a mark in the form of a variation of the material, which is characterized by a reduced permeability for electromagnetic radiation, without any fundamental variation that can be seen in some way on the surface of the body, characterized in that a certain wavelength of the laser-type light is used, to which the glass is partially transparent, and is less than t All the wavelengths of the laser light corresponding to the horizontal section of the transmission curve.
