Laser cleaning is the process of removing contaminants, debris or impurities (such as carbon, silicon and rubber) from the surface of a material by irradiating it with a laser beam. At low laser flux, the material is heated by the absorbed laser energy and evaporates or sublimates. At high laser flux, the material is typically converted to a plasma. Compared to many traditional approaches, laser cleaning is a more low-cost and environment-friendly technology.
It involves no solvents or chemicals. In addition only removed materials need to be disposed of. Laser cleaning also offers benefits such as a great deal of control over the beam (meaning you can achieve the desired depth that you want to), increased precision and improvements in process speed, so there are many advantages to be considered. That's why it's being introduced to more and more industries and is taking the place of traditional cleaning methods such as dry-ice blasting and media blasting.
