The technology
What is laser cleaning?
Laser cleaning is a modern and highly effective method of removing contaminants, coatings, rust, paint, and other unwanted substances from surfaces using focused laser beams. It has gained popularity across industries thanks to its precision, efficiency, and environmentally friendly nature.
How laser cleaning works
- 01
Laser generation
A laser beam is generated using a fiber, solid-state, or CO2 laser. The choice depends on the specific cleaning requirements and the material being treated.
- 02
Absorption of laser energy
The beam is directed at the surface. Contaminants absorb the energy, heat up, and undergo a process called photothermolysis.
- 03
Contaminant vaporization
As contaminants absorb energy they vaporize or sublimate — passing directly from a solid or liquid state to a gas.
- 04
Gentle removal
Vaporization removes contaminants without damaging the underlying substrate — selective, precise, non-abrasive.
- 05
Environmental benefits
A dry, non-contact process — no chemicals, no solvents, no abrasives. Minimal waste and a genuinely green solution.
- 06
Control & automation
Power, pulse duration, and scanning speed can be tuned to each application for consistent, repeatable results.
Applications of laser cleaning
- Industrial cleaning — rust, paint & contaminants from metal
- Restoration — artifacts, sculptures & buildings
- Automotive — prep for painting or coating removal
- Aerospace — delicate components without integrity loss
- Electronics — oxides and residues on components
- Marine — ship hulls and marine equipment
Laser cleaning offers a precise and efficient alternative to traditional cleaning methods — contributing to improved quality, reduced environmental impact, and increased productivity across industries.
