The biggest advantage of pulsed fiber laser cleaning and removing is that it has a very limited impact on the base materials, with laser pow
This selective vaporization usually occurs when the laser beam absorption rate of the contaminants on the surface is significantly higher than the one on the substrates. One typical application case is the cleaning of dirt on the stone surface. The contaminant on the stone surface has a high absorption rate of the laser and is quickly vaporized. When the contaminants are cleaned, the absorption rate to the stone surface is very low.
Most of the laser energy is scattered to the contaminant on the stone surface, and the temperature change of the stone surface is very small. Therefore the stone surface is thus protected from damage while the contaminants are removed.
