Laser ablation (scientific name for laser cleaning) or light ablation is the process of removing material from a solid (or sometimes liquid) surface by irradiating it with a laser beam. At low laser flux, the material is heated and evaporated or sublimated by the absorbed laser energy. At high laser fluxes, materials typically convert to plasma. Generally, laser ablation refers to the removal of material using a pulsed laser, but if the laser intensity is high enough, a continuous wave laser beam can be used to ablate the material. Excimer lasers with deep ultraviolet light are mainly used for optical ablation. The laser wavelength used for optical ablation is approximately 200 nm. The depth of absorbed laser energy and the amount of material removed by a single laser pulse depend on the optical properties of the material, as well as the laser wavelength and pulse length. The total mass of each laser pulse ablated from the target is commonly referred to as the ablation rate. Laser radiation characteristics such as laser beam scanning speed and scan line coverage significantly affect the ablation process.

In simple terms, lasers are no different from the accompanying light (visible and invisible) around us, except that lasers use resonators to concentrate light in the same direction and have better performance than simple wavelengths, such as coordination, etc. Therefore, in theory, all wavelengths of light can be used to form lasers, but in fact, due to the limited number of media that can be excited, Therefore, the ability to generate stable and suitable laser light sources for industrial production is quite limited. The widely used lasers are probably Nd: YAG lasers, carbon dioxide lasers, and excimer lasers. Due to the fact that Nd: YAG lasers can be transmitted through optical fibers, which is more suitable for industrial applications, they are also widely used in laser cleaning.
