Principles and methods of laser cleaning
1. Selective heating:Laser energy can be selectively absorbed by the target material without causing damage to the substrate. This selective heating is the core principle of laser cleaning.
2. Instant high temperature effect:
After the laser is focused, an extremely high instantaneous temperature will be generated on the surface, causing the contaminants to be cleaned to quickly vaporize and peel off.
3. Shock wave effect:
The instantaneous high temperature generated by laser action will trigger local explosive evaporation and generate shock waves, thereby further promoting the stripping of contaminants.
Main cleaning methods:
1. Pulse laser cleaning:
Use high-power, short-pulse laser to irradiate the target surface, cleaning contaminants through instantaneous high temperature and shock wave effect.
Laser cleaning relies on the selective heating and shock wave effect of high-energy beams to quickly and effectively clean various surface contaminations and is widely used. If you have further questions, please feel free to ask.
