Laser cleaning is an advanced green cleaning technology that utilizes high-energy laser beams to irradiate the surface of objects, removing contaminants through effects such as photothermal and photochemical processes. Characterized by non-contact, high precision, and pollution-free features, it is widely applied in industrial manufacturing, cultural heritage preservation, and other fields.

core principle
The core of laser cleaning lies in the selective absorption of materials and the instantaneous conversion of energy
Selective absorption: Choose a laser wavelength easily absorbed by contaminants but poorly absorbed by the substrate, ensuring the energy primarily targets the pollutants while protecting the substrate.
Instantaneous Energy Conversion: Pollutants absorb laser energy and convert it into thermal energy within an extremely short time (nanoseconds/picoseconds), causing the pollutants to evaporate, detach, or decompose instantly.
Removal mechanism: The cleaning is primarily achieved through photothermal effects (thermal expansion, vaporization), photochemical effects (ultraviolet laser breaking molecular bonds), and shock wave effects.
