Optical Materials for Laser SystemsGallium Laser Cleaning Settings
When laser cleaning gallium, you'll want to approach it unlike harder metals such as steel or titanium, which handle intense heat without issue. Gallium's unusually low melting point sets it apart, risking surface liquefaction if energy builds up too quickly. Start with reduced power and faster scan speeds to strip away oxides or residues while keeping the material solid. Make sure you avoid prolonged exposure in one spot, as this can cause uneven melting and distort the underlying structure. This method exposes a clean, intact surface ready for semiconductor or medical applications.

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.
