What is laser cleaning
Principle of surface laser cleaning

The coating is removed by absorbing the focused laser energy

The laser pulse with high energy but short time has little effect on the surface of the substrate

The laser is reflected on the blank substrate surface, and the stripping process is over

With the right laser parameters and optimal wavelength, the metal material will not be damaged or melted

Two physical actions
Coating is vaporized (falling off due to sublimation)
Removal due to pressure due to high temperature
