Regarding the laser cutting processing solutions for inorganic brittle optical materials such as glass cover plates, Strong Laser uses ultra-fast laser cutting heads and Bessel laser beam shaping cutting technology. The laser forms a certain depth of internal burst zone inside the transparent material. The stress in the burst zone spreads to the upper and lower surfaces of the transparent material, and then the material is separated by mechanical or CO2 laser.

Compared with the traditional CNC cutting process, the cutting of Strong Laser has the following advantages: narrow cutting seam, less deformation of the work piece; non-contact processing, no stress damage; high-speed special-shaped cutting, direct penetration, high efficiency; no cutter wheel Wear of grinding head, no debris and oil, clean processing, etc.

For engraving and marking solution，Strong adopts femtosecond laser coloring process to realize the processing of dark markings inside the glass without damaging the structure of the material. The main principle is to focus the femtosecond laser inside the glass and select a light intensity below the material damage threshold, so that the glass will change the absorption coefficient and refractive index of the glass material irradiated by the laser, resulting in darkening or discoloration. After multiple femtosecond laser irradiation (scanning), the irradiated part of the glass becomes deeper and finally stabilizes.

Strong laser engraving and marking solution wouldn’t damage the surface of the glass and the glass wouldn’t appear micro-cracks, so it wouldn’t affect the original strength and product quality of the glass; at the same time, this processing technology wouldn’t change the chemical composition of the glass.

The strong laser engraving and marking solution has successfully realized the laser engraving and marking of online product codes and shipping product codes.

The Strong laser cutting machine for camera/watch cover is specifically for this solution. According to the principle of ablation cutting on the surface, the high-peak power laser beam is focused on the surface of the material, and its surface is repeated repeatedly to be ablated. The material is instantly heated by the high-density, peak and high-power laser, and the temperature rises rapidly to the vaporization temperature. Then the material is gradually ablated by the laser and escapes in the form of gas, so as to realize the cut-through separation of the material.
