CO2 lasers operate by emitting infrared light and are ideal for non-metal materials like wood, glass, textiles, and certain plastics. They excel in applications requiring clean, high-contrast marks. CO2 lasers are widely used in packaging, signage, and the textile industry due to their ability to create intricate designs and text on organic and synthetic materials.
3.UV Laser Marking
Ultraviolet lasers, also known as “cold lasers,” operate at a shorter wavelength and produce high-contrast marks on sensitive materials without causing thermal damage. UV lasers are indispensable in the electronics and medical device sectors, where precision and minimal material impact are crucial. They are particularly effective for marking small components and delicate surfaces.
4.Green Laser Marking
Operating at a wavelength of 532 nm, green lasers are well-absorbed by reflective materials like copper and gold. This technology is valuable in the semiconductor and electronics industries, where precision and clarity are paramount. Green lasers are also used for marking glass and some plastics, offering high-quality, crisp markings.
Recent Advancements in Laser Marking Technology
Laser marking technology continues to advance, offering new capabilities and improved performance:
1.3D Laser Marking
This advanced technology allows for marking on curved and irregular surfaces, expanding the range of applications. It is particularly useful in industries such as automotive and aerospace, where components often have complex shapes.
2.High-Speed Laser Marking
Enhanced laser sources and improved optics have led to significant increases in marking speeds. High-speed laser marking is critical for mass production environments, where efficiency is key.
3.Color Laser Marking
Recent advancements have made it possible to create colored marks on metals using laser technology. By adjusting laser parameters to create nanostructures on the material’s surface, these lasers can produce a spectrum of colors, opening new possibilities for branding and decorative applications.
Innovations in Portable Laser Engravers
A significant advancement in laser marking technology is the development of a portable laser engraver. These devices bring the power of laser marking to new levels of convenience and flexibility.
