2.How Do Laser Cleaners Work?

2.1 The Science Behind Laser Cleaning

Laser cleaning operates on the principles of laser ablation and photothermal effects. Here’s a breakdown of the science behind it:

  1. Laser Ablation: The laser emits a highly focused beam of light that is absorbed by the contaminants on the surface. This energy absorption causes the contaminants to rapidly heat up and vaporize or dislodge from the surface. The underlying material remains largely unaffected due to its different absorption characteristics or the control of laser parameters.

  2. Photothermal Effects: The energy from the laser is converted into heat upon absorption by the contaminants. This localized heating causes thermal expansion, leading to the breaking of bonds between the contaminants and the surface. This effect is particularly useful for removing rust, paint, and other coatings.

  3. Photomechanical Effects: The rapid heating and subsequent cooling create a shock wave that helps to further dislodge contaminants. This is especially effective for cleaning surfaces with multiple layers of contaminants.
