How Laser Cleaning Machines Work

Basic Principles of Laser Cleaning

Laser cleaning is a non-contact and non-abrasive process that uses laser beams to remove contaminants from surfaces without damaging the underlying material. The process works by focusing a high-energy laser beam on the surface to be cleaned. When the laser hits the contaminant layer, it rapidly heats it, causing the material to vaporize, sublimate, or break down into smaller particles, which can then be blown away or extracted. This selective process ensures that only the unwanted material is removed while preserving the base surface, making it ideal for delicate and sensitive applications.
One of the key benefits of laser cleaning is its precision and control. Operators can adjust laser settings such as wavelength, pulse duration, and intensity to target specific contaminants. This makes it suitable for a wide range of applications, from rust removal on industrial machinery to paint stripping on aircraft, and even the delicate cleaning of historical artifacts.
