End-pumped lasers marking non-metallic parts in the automotive field

0 comments

Most of the non-metallic materials in the automotive industry are black plastics, and the material is relatively simple. When processing such components with fibre lasers, the colour is often grey-black, the contrast is not good, and the scorch marks are serious. But the 1064nm end-pumped laser with high peak power produces whiter colours, more apparent contrast, and lower cost; hence, it is much more suitable!

Tips:

The pulse width of the end-pump laser is 6~20ns, so the lower thermal effect and higher peak power are very advantageous in marking non-metallic materials. Although it cannot be compared with the ultraviolet laser or fibre laser, the advantage of the end-pump laser is undeniable.

The pulse width of the fibre laser is too broad, and the peak value is too low, making it advantageous only in metal processing but not non-metal processing.

End-pumped lasers

Application Advantages:

  • An 8W cold light laser has ultra-high peak power and is six times the peak power of a 20W fibre laser.
  • Narrow pulse width, low heat, no burning of plastic
  • Anti-high reflection, gold/silver/copper marking does not damage the laser
  • High precision, more delicate than fibre laser processing
