Ablation

Definition

Ablation is the process of removing material from a surface by vaporization, chipping, or other erosive processes. In laser cleaning and decontamination, ablation uses focused laser beams to effectively remove unwanted contaminants, coatings, or materials without damaging the underlying surface. This precise method is efficient and environmentally friendly, making it a popular choice for cleaning various substrates in diverse applications.
