Laser Cleaning System

Laser Cleaning Process Mechanism:

a) The laser beam emitted by the laser source is absorbed by the contaminant layer on the surface to be treated.

b) The absorption of high energy rapidly generates a plasma (a highly ionized, unstable gas), which expands abruptly and produces a shockwave.

c) The shockwave fragments the contaminants and removes them from the surface.

d) The laser pulse duration must be sufficiently short to prevent heat accumulation that could damage the underlying substrate.

e) Experiments show that when oxides are present on a metal surface, plasma is generated directly at the metal surface.

Plasma is generated only when the energy density exceeds a certain threshold, which depends on the type of contaminant or oxide layer being removed. This threshold effect is crucial for achieving effective cleaning while ensuring the safety of the substrate material. A second threshold also exists: if the energy density exceeds this higher threshold, the substrate itself will be damaged. Therefore, to enable efficient and safe cleaning, laser parameters must be carefully adjusted so that the energy density of the laser pulses remains strictly between these two thresholds.

Advantages of Laser Cleaning:

Environmentally friendly: Compared to traditional cleaning methods, laser cleaning produces no waste liquids, gases, or other byproducts requiring secondary treatment. 

Low operating cost: Requires only a one-time investment with no consumables. 

Compact and portable: Ready to use instantly, occupies minimal space, offers high operational flexibility and mobility. 

User-friendly: Minimal training required—operators can be qualified after simple instruction. 

Minimal substrate damage: Gentle on the base material, preserving its integrity.
