What Is Laser Cleaning?

Laser cleaning is the process of removing undesired material from a solid surface by irradiating it with a laser beam. By absorbing the energy of the laser beam, the targeted material will either turn into a gas and evaporate or the pressure of the interaction will cause the contaminants to break free from the surface. As the surface below does not absorb any energy, it stays untouched. Our laser cleaning technology is safe and eco-friendly.

How Does It Work?

Laser cleaning works by shooting nanosecond-length pulses of laser light at undesired material, turning the particles into gas that’s either vaporised and/or vacuumed away. A fume extractor is used to capture the vaporised residues as they are removed for a dust free process with minimal clean-up. As the surface below does not absorb any energy, it stays untouched, resulting in zero damage The equipment is designed for safe use in a wide range of applications. For personnel safety, the operator, and nearby observers, wear special laser safety glasses that provides comfortable eye protection, in addition to other simple to implement procedures.

Laser Cleaning Works In The Following Way:

  1. The laser sends short pulses of infra-red light to the surface
  2. The contamination absorbs the laser light
  3. The contamination heats up very quickly
  4. The substrate remains cool
  5. The difference in temperatures causes the contamination to either turn into a gas or the pressure of the interaction will cause particles “shred away” from the surface
  6. Any remaining residue can be vacuumed off
  7. Result: a clean, untouched surface restored to its original condition.
