Abstract

The invention discloses an instant glass developing technology under pulsed laser action. The instant glass developing technology comprises the following steps: according to the component expression being xB2O3.y PbO.z SiO2.18Bi2O3.2Sb2O3, weighing a silicon-containing compound raw material, a boron-containing compound raw material, a lead-containing compound raw material, a bismuth-containing compound raw material and an antimony-containing compound raw material, and uniformly grinding to form a mixture; performing pretreatment for 1-3 h at 400-500 DEG C, and performing cooling and cutting; and fixing cut glass on a sample platform of an pulsed laser engraving machine, selecting a picosecond or nanosecond pulsed laser beam to vertically irradiate the interior of the cut glass, controllingthe power of the pulsed laser beam, and performing mobile scanning in the interior of the cut glass by the pulsed laser beam according to the set pattern trajectory to obtain a three-dimensional developing pattern directly. According to the invention, through the increase of the lead content in a glass component or the increase of the power of pulsed laser to deepen glass developing, instant glass developing under the pulsed laser action is realized.

Description

technical field [0001] The invention relates to a color development technology, in particular to a glass instant color development technology under the action of a pulsed laser, and belongs to the technical field of laser processing. Background technique [0002] Laser has been widely used in the field of micromachining. Compared with continuous lasers, pulsed lasers have smaller thermal effects, lower operation and maintenance costs, higher pulse repetition frequency and energy, and can achieve high-quality and high-efficiency microstructure processing. [0003] At present, the technology of using pulsed laser to make glass color is mainly divided into two categories: one is to dope noble metal ions inside the glass, use pulsed laser to perform micromachining inside it, and then provide energy for migration and diffusion of ions after heat treatment, The precious metal ions are aggregated and deposited into particles, so that they develop color inside the glass.
