The difference between UV laser and fiber laser marking

Release time:2024-04-18 16:14:03

【summary】

UV laser and fiber laser both have their own advantages and suitable scenarios in marking applications. How to choose the right laser type depends on the specific needs of the customer, including the type of material to be marked, the required marking effect, the production environment and budget.

UV laser and fiber laser are two commonly used laser technologies for marking, and they have some significant differences in the marking process.

Wavelengths of UV and fiber lasers

UV laser: The wavelength of UV lasers is generally between 200 and 400 nanometers. UV laser has a shorter wavelength and can produce a high-energy beam, which is suitable for fine marking on the surface of materials, especially in applications that require high resolution and precision.

Fiber laser: The wavelength of fiber laser is usually between 1000 and 2000 nanometers. Compared with UV laser, fiber laser has a longer wavelength and more concentrated energy, which may be better for marking certain materials, especially when deep marking is required or heat-sensitive materials need to be processed.

The difference between power and energy

UV laser: Due to its short wavelength, UV laser can often provide higher energy density, which is suitable for rapid marking of materials in a short time, especially for hard materials or micro-marking that requires high precision.

Fiber laser: Although fiber laser has a longer wavelength, it uses fiber transmission and has less energy loss, so it can provide stable power output. For some applications that require stable and lasting marking, fiber laser may be more suitable.

Applicable materials

UV laser: UV laser can achieve good marking effect on most materials, including metal, plastic, ceramic, glass, etc. However, it should be noted that for some heat-sensitive or easily damaged materials, it may be necessary to control the laser parameters to avoid overheating.

Fiber laser: Fiber laser has a relatively long wavelength, and its marking effect on certain specific materials is more prominent, especially for deep marking or cutting of some metal materials.


In general, UV laser and fiber laser have their own advantages and suitable scenarios in marking applications. How to choose the right laser type depends on the specific needs of the customer, including the type of material to be marked, the required marking effect, the production environment and budget.
