Optical Materials for Laser SystemsZirconia Laser Cleaning Settings
The key with Zirconia is its strong laser absorption. We've found this makes cleaning efficient without much reflection loss. It removes contaminants quickly while preserving the surface. Unlike metals, its low thermal conductivity traps heat locally. We typically start with moderate power to prevent buildup. This approach reduces cracking risks in such a hard ceramic. Zirconia stands out for high toughness under stress. Adjust scan speeds higher for even exposure. In our experience, multiple light passes restore it fully. Watch for thermal gradients at the end, though, and cool between runs to avoid micro-fractures.

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.
