About P-Laser Canada
The illustration on the left shows the effects of laser cleaning. The grey layer on top op 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!
