Laser cleaning involves the use of a laser system. The laser emits a high-energy beam of light that is directed onto the surface to be cleaned.

The laser beam interacts with the contaminants or unwanted substances on the surface. These materials absorb the energy from the laser light, causing them to heat up rapidly.

The absorbed energy leads to either ablation or vaporization of the contaminants. Ablation refers to the process of removing material from the surface while vaporization involves converting the material directly into a gas.

One of the key advantages of laser cleaning is its ability to selectively remove specific materials without damaging the underlying substrate. This selectivity is achieved by adjusting the laser parameters such as power, pulse duration, and spot size.

Unlike traditional cleaning methods, laser surface cleaning does not require abrasive materials or chemicals. This makes it environmentally friendly and reduces the generation of secondary waste.

Laser systems offer precise control over the cleaning process, allowing operators to target specific areas and achieve the desired level of cleanliness. This precision is valuable in applications where accuracy is crucial.

Laser cleaning generates less heat compared to some other thermal processes, minimizing the risk of heat-induced damage to the material being cleaned.

Laser cleaning eliminates the need for some safety measures associated with traditional methods, such as the handling and disposal of abrasive materials or chemical waste.

Laser surface cleaning can be applied to various materials, including metals, plastics, ceramics, composites, and historical artifacts.
Laser surface cleaning finds applications in a wide range of industries, including manufacturing, automotive, aerospace, cultural heritage preservation, and more. It is used for tasks such as rust and corrosion removal, paint stripping, historical artifact restoration, and preparation of surfaces for welding or bonding.
While laser cleaning offers many benefits, it’s important to consider safety measures, including the use of appropriate laser safety eyewear, controlled access to laser areas, and adherence to safety standards and regulations. Additionally, the specific parameters used in laser cleaning depend on the type of material being treated and the characteristics of the contaminants, requiring expertise in laser system operation and optimization
