Laser cleaning application

A laser cleaning machine is a technology used to remove contaminants, coatings, rust, and unwanted materials from surfaces. The principle of laser cleaning involves several key steps:
1. Laser Source: Laser cleaning machines use a high-intensity laser source, typically a fiber laser or a pulsed laser, with a specific wavelength that matches the absorption characteristics of the material or substance to be removed.
2. Absorption of Laser Energy: When the laser beam interacts with the contaminant or unwanted material on the surface, the material absorbs the laser energy. This absorption causes a rapid increase in temperature at the target area.
3. Thermal Expansion and Ablation: The rapid temperature increase leads to thermal expansion and, in some cases, sublimation or vaporization of the contaminant or material. As a result, the substance is loosened or turned into a gas.
4. Pressure Shock Wave: The rapid expansion and vaporization of the material generate a pressure shock wave. This shock wave physically dislodges and removes the contaminant or unwanted substance from the surface.
5. Capture and Ventilation: The removed material is often captured by a ventilation or extraction system to prevent recontamination and ensure safe disposal.
6. Surface Preservation: Laser cleaning is a non-contact process, so the underlying substrate is minimally affected, preserving the integrity of the surface. It avoids the damage that can occur with abrasive methods or chemical cleaning.

The effectiveness of laser cleaning depends on the material to be removed, the type of laser used, the energy settings, and the appropriate safety measures, as laser systems can be powerful and potentially hazardous if not used correctly.
