Application - Laser Cleaning

Laser cleaning is the process by which contaminants, debris or impurities (e.g. carbon, silicon and rubber) are removed from the surface of a material by using laser irradiation. This is a low-cost and environmentally-friendly laser application technique, which is in widespread use throughout global industry.

There are two types of laser cleaning process, which are typically used:

  • One which is the removal of a layer on the surface of a material,
  • While the second is the removal of the entire upper layer of a material.

Industrial Uses


Laser cleaning is popular in a range of industries but especially in manufacturing where it is very often used to prepare surfaces for subsequent industrial processes such as painting and welding. It’s also a valuable for processes where working with materials such as glass, ceramics, metals, concrete and plastics, etc. are involved. The process  can also be applied to the cleaning of larger objects, e.g. rust removal on bridges or debris/contaminants removal on the surface of aircraft and trains, etc.



Laser cleaning applications use no solvents or chemicals so are a much more environmentally friendly approach compared to many traditional approaches to cleaning. In addition only removed materials need to be disposed of. Cleaning also offers additional benefits such as increased precision and improvements in process speed, so there are many benefits and advantages to be considered.

Laser Cleaning using SPI Lasers


SPI Lasers Fiber Laser range can be used for a variety of industrial laser cleaning applications, such as paint removal, preparation treatment, oil and oxides (e.g. rust) removal, mould cleaning, tool cleaning in addition to labelling and marking. Laser cleaning typically uses high repetition rates and short pulses with high peak powers. All of this is done without damaging the substrate materials and without making contact with the material surface.
