How to choose a good fiber laser cutting machine

If your company is in the manufacturing, electronics, or even medical sectors, sooner or later, you will require laser marking for your products and components. The best solution for this is a fiber laser marking machine. The non-contact fiber laser marking process is well-known among customers for the following reasons:

• Durability
• Readability
• High-temperature resistance
• Application to various materials
• No need for toxic inks, solvents, or acids

But simply understanding the advantages of fiber lasers is not enough. There are other factors that you need to consider.

Factors for Choosing a Fiber Laser Marking Machine:

The following are parameters specific to the laser source that you need to keep in mind when choosing a fiber laser marking machine.

• • Beam Quality: Beam quality is an important parameter, as it affects the laser’s processing capability. The reasons for the importance of beam quality are simple:
    • A laser with better beam quality can remove material much faster, with better resolution, and improved quality.
    • Laser markers with high beam quality can produce a focused optical spot size down to 20 microns or smaller.
    • High beam quality lasers are particularly suited for scribing and cutting materials such as silicon, aluminum, and stainless steel.

• • Single or Multi-mode Lasers: There are two types of fiber lasers – single mode and multi-mode.
  • Single mode fiber lasers deliver a narrow, high intensity beam that can be focused down to a spot size as small as 20 microns and are generated within a fiber core of less than 25 microns.
  • This high intensity is ideal for cutting, micro machining, and fine laser marking applications.
  • Multi-mode lasers (also called higher order mode), use fibers with core diameters greater than 25 microns. This results in a beam with a lower intensity and large spot size.Single mode lasers have the best beam quality, while multi-mode lasers allow for the processing of large components.

• • Mark Resolution: The type of fiber laser machine you choose will determine its mark resolution capabilities. The machine should be able to achieve a sufficient mark size and quality. Fiber laser marking machines generally consist of 1064nm lasers, which provide resolutions up to 18 microns.

These basic factors can help you make an informed decision when purchasing a fiber laser marking system for your company.
