Laser cleaning is essentially the process of clearing away undesired material from a solid surface by irradiating it with a laser beam. How does it work? Well, by absorbing the energy of the laser beam, the targeted material is heated very quickly, thus making it evaporate or sublimate, and since the surface below does not absorb any energy, it stays untouched.

Manipulating the laser flux, its wavelength and its pulse length, the amount of material that is being removed by a single laser pulse can be controlled with extreme precision. This makes laser cleaning equally suitable for rapid and deep rust removal as for removing a single thin layer of paint, without damaging the base coat.
