Fiber, CO₂, and UV Laser Marking Machines: Technical Comparison and Application Guide
When planning a laser marking investment, one of the most critical steps is accurately comparing fiber, CO₂, and UV laser technologies from a technical perspective. Each technology offers distinct advantages in terms of wavelength, material interaction, speed, and thermal impact. This content has been prepared as a technical comparison guide to help you choose the right technology. For Venox solutions: Laser Marking Machines.
Technical Fundamentals of Laser Marking Technologies
The primary difference between laser marking systems lies in the wavelength used and how the laser beam is absorbed by the material. This difference directly affects marking quality and application success.
Fiber laser marking machines
Fiber lasers typically operate at a wavelength of 1064 nm. Because this wavelength is highly absorbed by metals, fiber lasers provide high-contrast and high-speed marking on stainless steel, aluminum, and alloys.
CO₂ laser marking machines
CO₂ lasers have a wavelength of 10.6 µm. They are effective on organic and non-metal materials, delivering clear but surface-level marking on wood, glass, leather, cardboard, and certain types of plastics.
UV laser marking machines
Thanks to their short wavelength (355 nm), UV lasers create a “cold marking” effect. Thermal impact is minimized, making them the preferred choice for sensitive plastics and electronic components.
Thermal impact and surface integrity
Thermal effects are more pronounced in fiber and CO₂ lasers. UV laser systems, on the other hand, minimize surface deformation and offer advantages in micro and aesthetic applications.
Speed and suitability for mass production
Due to their high speed, fiber laser systems are the most commonly preferred technology in mass production lines. CO₂ and UV lasers are more often used for specialized applications.
