The present invention will be further described with reference to the working principle.
YAG laser cleaning process relies on the characteristics of the light pulse generated by the laser, and the principle of the photophysical reaction caused by the interaction among high-intensity light beam, short pulse laser and pollution layer is as follows:
a) the beam emitted by the laser is absorbed by a contamination layer on the surface to be treated.
b) The absorption of the large energy forms a plasma (highly ionized unstable gas) that expands sharply, creating a shock wave.
c) The shock wave causes the contaminants to become fragmented and rejected.
d) The optical pulse width must be short enough to avoid heat build-up that would damage the surface being treated.
e) Experiments have shown that plasma is generated at the metal surface when there is oxide on the metal surface.
The plasma is only generated at an energy density above a first threshold, which depends on the contamination or oxidation layer being removed. This threshold effect is important for effective cleaning with substrate material secured. There is also a second threshold for the presence of plasma. If the energy density exceeds this threshold, the substrate material will be destroyed. In order to perform effective cleaning while ensuring the safety of the substrate material, the laser parameters must be adjusted to keep the energy density of the light pulses strictly between two thresholds.
Each laser pulse removes a thickness of the contamination layer. If the contamination layer is relatively thick, multiple pulses are required to clean. The number of pulses required to clean the surface depends on the degree of surface contamination. One important result produced by the two thresholds is the self-control of the cleaning. Light pulses with an energy density above a first threshold will reject contaminants until the substrate material is reached. The substrate is not damaged because its energy density is below the damage threshold of the substrate material.
When the laser cleaning machine is used, pollutants on the surface of an object absorb laser energy, are gasified and volatilized, and are expanded by instant heating, so that the adsorption force of the surface of the machine body to pollutant particles is overcome, and the pollutants are separated from the surface of the object.
The invention is applied to the laser cleaning, surface texturing and other processes in the fields of automobiles, railways, ships, metallurgy, petrifaction, national defense, aerospace and the like.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
