Each laser pulse removes a certain thickness of contamination layer. If the contamination layer is thick, multiple pulses are required for cleaning. The number of pulses required to clean the surface depends on the degree of surface contamination. An important result of the two thresholds is the self-control of cleaning. A light pulse with an energy density higher than the first threshold will continue to remove contaminants until it reaches the substrate material. However, because its energy density is lower than the damage threshold of the substrate material, the substrate will not be damaged.

The traditional laser cleaning industry has a variety of cleaning methods, mostly using chemical and mechanical methods for cleaning. Laser cleaning is considered to be the most reliable and effective solution due to its characteristics of no grinding, non-contact, no thermal effects, and suitability for objects of various materials. At the same time, laser cleaning can solve problems that cannot be solved using traditional cleaning methods.
