Abstract (en)

The present invention applies to technology of a laser treatment for the solid materials, in particular, to the technology of image formation into volume of the transparent wares with different colour effects. In comparisons with the known methods of formation of three-dimensional intra-volume images that consist in the focusing of a laser radiation to the prescribed point into volume of transparent sample, its irradiation with power density that exceeds the threshold value of volume breakdown of the material and a movement of the sample relatively to a laser beam according to prescribed law, this submitted method ensures a possibility to form the three-dimensional coloured intra-volume images. To achieve the above technical result in the mentioned method for formation of three-dimensional intra volume images, every dot of forming image into transparent sample is fired with the focused laser radiation with a power density that exceeds the threshold value of optical volume breakdown of the material. But as distinct from the prototype, a porous material is used as a transparent material, and that porous stuff contains, at least, one substance that changes irreversibly its physical and chemical characteristics by influence of factors of optical volume breakdown into volume of a transparent material.
