Different Applications of Laser Cleaning

Laser cleaning finds extensive applications in various industries such as shipbuilding, automotive repair, rubber molds, high-end machine tools, railways, and environmental protection. It offers an efficient solution for the removal of resin, paint, oil, stains, dirt, rust, coatings, platings, and oxide layers from the surfaces of objects.

Composite Laser Cleaning: A Versatile Solution


Composite laser cleaning serves as a versatile solution for specific cleaning needs. In cases where thick coating materials require laser cleaning, using a single high-output laser with multiple pulses can be expensive. However, employing pulse laser-semiconductor laser composite cleaning allows for swift and effective enhancement of cleaning quality without causing damage to the substrate. Moreover, when dealing with high-reflective materials like aluminum alloys, the reflectivity of a single laser poses a challenge. In such situations, pulse laser-semiconductor laser composite cleaning can significantly increase the energy absorption rate of the metal surface's oxide layer. The semiconductor laser's heat conduction facilitates quicker and more efficient stripping of the oxide layer by the pulse laser beam. This approach enhances the paint removal efficiency by more than twofold.

CO2 Laser Cleaning: Ideal for Non-Metallic Materials


The CO2 laser, which utilizes CO2 gas as its working substance, offers exceptional capabilities for cleaning non-metallic materials. By filling it with CO2 gas along with auxiliary gases like helium, nitrogen, and a small amount of hydrogen or xenon gas, the laser exhibits excellent directionality, monochromaticity, and frequency stability. Its unique wavelength makes the CO2 laser an excellent choice for removing glue, coatings, and ink from surfaces. For instance, when removing a composite paint layer from the surface of an aluminum alloy, a CO2 laser ensures the preservation of the anodized oxide film's surface and thickness. Lianwin Laser provides comprehensive laser cleaning solutions, including PCB ink cleaning in the 3C industry, roll cleaning of electrode plates for new energy power batteries, and customized soft pack earpiece sealing.

UV Laser Cleaning: Precision and Versatility


UV lasers, comprising excimer lasers and solid-state lasers, are widely employed for laser micromachining. Their short wavelength and high single-photon energy allow them to break chemical bonds directly between materials, resulting in the stripping of material from the surface in gaseous or particulate form. UV lasers excel in micro-manufacturing processes, offering a minimal heat-affected zone. Their unique advantages are particularly significant for semiconductor materials like Si and GaN, optical crystals such as quartz and sapphire, and high-polymer materials like polyimide (PI) and polycarbonate (PC). In the precision electronics industry, UV lasers stand out as the preferred laser cleaning solution. Their fine "cold" processing technology enables the treatment of surfaces without altering the physical properties of objects. Consequently, UV lasers find extensive applications in various sectors, including communication, optics, military affairs, criminal investigation, and medical care. For example, with the advent of the 5G era, there has been a surge in demand for FPC processing. UV lasers enable precise cold processing of materials, making them invaluable in this field.

Continuous Fiber Laser Cleaning: Sustained Performance


Continuous fiber lasers operate based on the principle of pump light entering the gain medium through a reflecting mirror. The gain medium, a rare-earth-doped fiber, absorbs the pump light. Consequently, the rare-earth ions within the gain medium undergo a level transition and achieve particle number inversion. Following inversion, the particles pass through the resonant cavity and transition from an excited state to a ground state. This process releases energy, resulting in a stable laser output. The key advantage of continuous fiber lasers lies in their ability to emit light continuously, making them highly efficient for prolonged cleaning operations.
