When it comes to lasers, most people think of the indestructible high-energy laser beam. If it is used for cleaning, the first thing everyone considers is whether the high-energy laser will damage the substrate.

We must first understand the principle of laser cleaning.

The essence of laser cleaning is actually the complex physical and chemical interaction between the laser and the dirt layer, that is, through continuous or pulsed laser laser to overcome the bonding force between the dirt and the surface of the substrate, the dirt is separated from the surface of the substrate to achieve the purpose of cleaning.


The continuous or pulsed laser with high brightness and good directionality is formed by optical focusing and spot shaping to form a laser beam with a specific spot shape and energy distribution, and irradiate it to the location of the contaminated material that needs to be cleaned, and the contaminant material attached to it After absorbing laser energy, a series of complex physical and chemical processes such as vibration, melting, burning, and even gasification will occur, and finally the pollutants will be separated from the surface of the material without damaging the material itself. Even if the laser acts on the cleaned surface, most of it is reflected off and will not cause damage to the substrate.

In principle, laser cleaning will not cause damage to the substrate. In actual operation, on the premise of achieving the ideal cleaning effect, will it cause damage to the substrate?
