Laser dust removal is the process of removing dust from a surface using laser ablation. Any types of dusts produced in work environments can be removed, such as metallic, plastic and organic dust. As the laser beam irradiates the surface, burnt off dust is vaporized and extracted using a dust extraction nozzle
Another emerging application is surface texturing. As the name suggests, this process aims at creating a specific texture on an object by using laser ablation to modify the surface finish. Such laser application allows increasing surface adherence when dealing with glued assemblies. Here is a list of popular applications for laser cleaning:
Laser ablation integrated with Laser Induced Breakdown Spectroscopy, a process control to analyse the target surfaces before and immediately after laser cleaning to verify the absence of unwanted residues; Simple means for end users to decouple and exchange fiber optic cables ; Nuclear-rated glovebox to safely decontaminate small parts
Laser ablation is the essence of laser cleaning process. It can be applied on glass, ceramics, metals, concrete, plastics, injection molds, cast parts for removing paint from metal and polychrome surfaces, stripping insulations from conductors and de coating paint from delicate surfaces with minimal impact on the base material .
Laser cleaning (also known as laser ablation) is a much safer alternative to traditional abrasive blasting methods. Laser blasting aims at increasing productivity and speed while protecting workers from the hazards of abrasive blasting materials. Laser technology is also significantly better for the environment when compared to traditional technology. This makes laser cleaning an ideal solution across a wide variety of surface cleaning applications like removing rust, paint removal ...
An ultra short pulsed Nd:YAG laser was employed to study the ablation effects and laser beam transport in optical fibres. Using 13 µm Zn coated carbon steel as a target, the relationship between ablation rate and laser fluence was investigated, and optimal processing conditions were determined.

This is how cleaning with the laser works. Marking lasers as well as short or ultrashort pulse lasers are used for surface cleaning with lasers. The operating principle is always the same: Pulse by pulse, the focused laser beam removes impurities such as oxidation or functional layers which hinder the joining process.
CW lasers can also be used in laser ablation but pulsed lasers are more common. This process can be used to remove a layer of paint from a surface or contamination from surfaces of statues and historical monuments. Hence, laser cleaning refers to removing contaminants from surfaces by the use of laser ablation. Figure 1 below shows the laser ablation process through which the materials from the surface are vaporized.
Laser Cleaning or Laser ablation is the process of removing material from a solid (or occasionally liquid) surface 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 plasma.
Laser cleaning and ablation. When cleaning a surface, we are primarily interested in the removal of an unwanted layer with minimal impact to the underlying bulk material. Existing processes for this include mechanical brushing, sand or grit blasting, and chemical or dry ice treatment.
The DIHORSE 50W hand-held laser cleaning machine comes with a laser pulse intensity of 0.1 Watt/m2, which is just strong enough to ablate the surface without damaging the substrate. Laser module life The Dihorse-designed laser cleaner guarantees up to 100,000 hours of laser ablation.
Laser cleaning a tire mold. The high-performance short-pulse lasers from the TruMicro Series 7000 are based on disk laser technology and combine short pulses with high pulse energies, even with high frequencies. This allows you to remove layers and contamination with utmost speed, and reduce your cycle times.
The laser cleaning process (laser ablation) consists in evaporating the layer of material that must be removed from the surface of the solid body. This layer can be, for example, contamination, corrosion or paint coating. The vast majority of the energy within the laser beam is absorbed by the removed layer, thanks to which the substrate ...
Industrial laser cleaning - or ablation - is the process of clearing away undesired material from a solid surface by irradiating it with a laser beam. By absorbing the energy of the laser beam, the targeted material is heated very quickly, making it evaporate or sublimate. As the surface below does not absorb any energy, it stays untouched.
Also called laser ablation, laser cleaning uses thousands of focused laser pulses per second to break down and remove contaminants from the surface. The laser light absorbs surface materials and breaks down the chemical bond, allowing it to safely and effectively remove rust, oil, mold, and other contaminants.
Using multiple achieving even greater processing efficiency of laser ablation fibres arranged in 2 rows, as shown in Fig. 3(a), and keeping surface cleaning. the size of the focused beam spot unchanged to keep laser power twice as high as before, we can assess that cleaning References efficiency increases 2.5 times from Eq.
Laser Ablation is the removal of material from the surface of a part. Large-area ablation examples include paint removal and surface cleaning. Smaller feature laser ablation is used in thin film patterning, blind-hole and shaped feature drilling as well as localized conformal coating removal. Laser technology provides the flexibility for application optimization, whether this is precisely delineating the surface area to be removed, the depth of material removal, or the speed of the process.
An optical box containing mirrors for specially directing laser light, such as repeated pulsed CO 2 laser, is mounted in a hand-held cleaning head or in a custom work head. The hand-held cleaning head can be used to safely direct laser energy to a surface to be cleaned; the laser beam ablates from the surface coatings, corrosion, and the like ...
Laser paint removal works through a process known as laser ablation. Laser energy is released in short pulses at a set repetition rate. In doing so, the pulsed laser generates shockwaves that eject coatings from metal surfaces when they reach their ablation threshold. As the paint is vaporized, the surface is left intact.
The Ablation LaserCell is a Class 1 workstation providing cleaning, film removal and surface roughness modification for manufacturing, refurbishment and repair applications. Fully automated with a pre-loaded library of standard processes, it eliminates the need for cleaning media and dramatically reduces the amount of solid waste compared to traditional techniques.
Laser cleaning works on the principle of laser ablation, by which individual molecular bonds are broken down and released from the surface. Thanks to high intensity laser pulses of a few nanoseconds, the surface impurities are heated very quickly, which causes evaporation, but also creates local explosions that remove the impurities from the surface.
Using multiple achieving even greater processing efficiency of laser ablation fibres arranged in 2 rows, as shown in Fig. 3(a), and keeping surface cleaning. the size of the focused beam spot unchanged to keep laser power twice as high as before, we can assess that cleaning References efficiency increases 2.5 times from Eq.
