When laser cleaning basalt, it stands out from softer stones like limestone because of its dense, hard nature. I've seen this density help absorb laser energy quickly, so contaminants lift off without much residue left behind. That makes the process efficient for tough buildup in construction or heritage sites. But watch out mid-way—basalt tends to fracture if heat builds unevenly, unlike those porous limestones that just fizz away. This works best when you keep passes steady and overlap spots well, solving the brittleness by spreading the energy. In my experience, it preserves the stone's strength for marine or aerospace uses, avoiding cracks that could weaken structures later. Just ease into higher intensities gradually to handle its heat resistance without surprises.

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.
