Optical Materials for Laser SystemsCedar Laser Cleaning Settings
When laser cleaning cedar, we typically begin by selecting a low-power setting to match its soft, porous structure. This wood absorbs laser energy readily because of its low reflectivity, which allows contaminants to vaporize without much resistance. We've found that starting with a focused spot size helps expose surface layers evenly, reducing the risk of uneven cleaning on its lightweight frame. As you proceed, maintain a moderate scan speed to account for cedar's poor heat conduction—heat tends to localize and can char the material if you push too fast. In our experience, this calls for two passes with significant overlap to restore the wood's natural grain without embedding residues in its open pores. Watch out for overexposure in the middle of thicker sections, where porosity traps moisture and amplifies thermal buildup; dial back the energy density there to avoid splintering. Overall, these adjustments preserve cedar's flexibility for applications like furniture restoration or heritage work.

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.
