Ultrafast Laser Physics and Material InteractionsPolytetrafluoroethylene Laser Cleaning Settings
When laser cleaning Polytetrafluoroethylene, watch its high reflectivity right away. It reflects light much more than typical plastics, slowing the process down. Start low on power to build absorption gradually. I've seen multiple passes work best here. Unlike conductive metals, its poor heat spread risks local burns, so keep scans quick. This restores surfaces cleanly without warping.

Parameter Relationships
Shows how changing one parameter physically affects others. Click any node to see its downstream impacts and role.
Power Range
Amplifies damage risk in Pulse Width and Energy Density. Keep low to maintain safety margins.
Spot Size
Same power in a smaller spot creates much higher energy density.
Energy Density
Higher power delivers more energy per pulse, removing more material.
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.
