Optical Materials for Laser SystemsChromium Laser Cleaning Settings
When laser cleaning chromium, watch out for its high reflectivity, which scatters more energy than you'll see with less shiny metals like iron or nickel. We've found this makes the process less efficient at first, so we typically start with controlled power levels to ensure the beam couples effectively without wasting shots. Unlike softer coatings that ablate easily, chromium's exceptional hardness demands a focused approach to avoid uneven removal that could expose underlying layers prematurely. In our experience, this reflective nature sets it apart in applications like stainless steel production or wear-resistant tooling, where we adjust scan speeds to prevent overheating spots. We recommend multiple passes with good overlap to restore surfaces cleanly, reducing the risk of micro-cracks from thermal buildup. This way, you reveal a polished finish while preserving the material's corrosion resistance.

Power Range
Amplifies damage risk in Pulse Width. Keep low to maintain safety margins.
Spot Size
Same power in a smaller spot creates much higher energy density.
Pulse Width
More power means higher peak intensity. Too much can damage the material.
Pass Count
Using more passes means you can use lower power and still get the job done.
