How it works!
Laser cleaning technology is a high end cleaning solution which uses short pulsed laser light as a working medium.
As the light hits the surface the dirt layer and any oxides underneath will absorb the energy and evaporate or crimp off the substrate leaving no residues.
This action causes a plasma layer usually in the form of a smoke plume which is typically vacuumed away and captured in a filtered recovery unit.
The substrate (usually metal) will not absorb the energy very well which is why the substrate is not affected.
The illustration on the right shows the effects of laser cleaning. The grey layer on top of the base material is the contamination. This layer will absorb the laser energy very well, whereas the base material (steel, aluminum, wood, plastics…) will reflect most of the energy.
The laser is short pulsed, this means that the laser beam is comparable to small bullets of light, shooting at a frequency of around 200.000 pulses/second!
