Abstract

The present invention relates to a laser internal engraving device. The laser internal engraving device comprises a worktable used for bearing processing-waiting objects; a laser generator used for producing a laser beam with a prescheduled wavelength; a laser beam converging mechanism used for converging the laser beams to the subsurface of the processing-waiting object to form a laser converging point which is capable of destroying the innate features of the processing-waiting object; a transmission mechanism used for transmitting the laser converging point according to the processing-waiting object, and the working wavelength of the laser beam is in the ultraviolet range. With the structure, man-made crystal, and the relatively strong absorption of the glass to the ultraviolet wave band, the volume of the burst point produced in the object is smaller; the generated pattern is more delicate and vivid.

Description

【Technical field】 [0001] The invention relates to an internal engraving device, more particularly to a laser internal engraving device which uses a laser beam to form a mark inside a material. 【Background technique】 [0002] In the past ten years, in the laser engraving process, the traditional laser beam with a wavelength of 1.06 μm or 0.532 μm is usually used. Convergence points, and form tiny visible burst points by changing the internal properties of transparent matter. By using an appropriate transmission mechanism to drive the converging point in the transparent material, a series of lifelike inner carving patterns or symbols can be formed inside the transparent material such as artificial crystal and glass. However, the burst spots formed by laser beams with traditional wavelengths are generally large in size, with a diameter of about 50-200 μm, or even larger. When these bursting points are used to form a three-dimensional or two-dimensional planar pattern, the dis...
