Laser ablation refers to the process of using a high-energy laser beam to irradiate the surface of an object so that the material on the surface instantly heats up, melts, evaporates, or is directly vaporized. This process can quickly remove contaminants from the surface without damaging the substrate and is one of the core principles of laser cleaning.
2.1.2 The process of laser ablation
When a laser beam irradiates the surface of an object, the light energy is absorbed by the contaminants on the surface and converted into heat energy, resulting in the contaminants heating up rapidly. Depending on the laser energy, the contaminant can be melted, evaporated or even plasmaized and thus removed from the surface of the substrate. The laser ablation process is very rapid and can be completed in the nanosecond or picosecond level, so the heat affected zone on the substrate is very small.
