Laser cleaning is not one single technology. A pulsed source gives short, controlled energy bursts for precision and low heat input; a continuous-wave source removes heavy contamination faster on robust metals but needs more heat control. The right machine depends on substrate, coating, speed, safety enclosure and fume extraction.
Typical applications
Pulsed vs continuous wave
Pulsed systems reduce average heat input and give better selectivity. Continuous-wave systems can be faster on large steel surfaces but are less forgiving on sensitive materials.
Precision cleaning
Use pulsed laser for moulds, tooling, thin oxides, restoration and any job where the substrate must stay visually clean.
Fast steel cleaning
Use CW laser for rust and thick paint on robust steel structures after a test patch confirms the surface finish is acceptable.
Parameter control
Power, frequency, pulse width, scan speed and overlap change the result. We configure recipes by material, not by brochure.
Safety and extraction
Industrial cleaners are normally Class 4 laser systems. The project must include optical-density eyewear, controlled access, reflection control, training and local extraction for laser-generated airborne contaminants.
Fume capture
Paint, oil, rust and coatings can release fine particles and hazardous vapours. Capture the plume at source with proper filtration.
Controlled area
Plan screens or enclosures, warning signs and a trained operator before production use.
Test patch first
Every coating/substrate combination needs a test area before accepting time, finish and safety assumptions.

Implementation checklist
- Send photos, coating type, base material and required finish.
- Run a test patch and choose pulsed or CW based on the result.
- Define extraction, PPE, screens and operator training before delivery.
