Laser cleaning is an efficient surface treatment technology that uses high-energy laser beams to directly act on the surface of materials to quickly remove surface contaminants or coatings without damaging the raw materials. This process includes several key steps:

Laser emission: The laser cleaning machine generates a beam of high-energy laser, whose wavelength, energy density and pulse width can be adjusted according to different cleaning needs. This allows the laser to be optimized for different materials and contamination types.

Surface action: The laser beam is focused and irradiated onto the surface of the target material. The thermal effect of the laser will quickly heat the surface material, causing contaminants such as oil, rust or coatings to locally heat up to a temperature where they evaporate or decompose.

Removal of contamination layer: The heated contamination layer will quickly peel off and disappear from the surface of the substrate due to uneven thermal expansion or direct vaporization. No secondary pollution will be generated during the cleaning process.

Cooling and cleaning: After laser cleaning, the surface of the material will cool quickly. In some cases, it may be necessary to use an air blow or water flush to remove any remaining debris or dust.

The advantage of laser cleaning technology is its non-contact nature, which means it causes minimal physical damage to the substrate. In addition, due to its high degree of controllability, laser cleaning can precisely remove only the target contamination layer without affecting the surrounding uncontaminated areas. This technology is widely used in various industrial fields, including aerospace, automobile manufacturing, precision instrument manufacturing, and cultural relic restoration.
