Empirical Study of Laser Cleaning of Rust, Paint, and Mill Scale from Steel Surface

Novel procedure for studying laser-surface material interactions during scanning laser ablation cleaning processes on Cu-based alloys

“…Laser technology is widely used in materials processing for industrial applications: e.g., cutting and marking, drilling, welding, material ablation [1,2]. In particular, surface cleaning by laser ablation has applications in several fields: e.g., the stripping of paint for making barrier between the environment and the surface [2], the cleaning of oil lubricants, rust or paint from surfaces in steel manufacturing [3,4], the elimination of carbonaceous deposits on engine parts [5]. And of course, the removal of continuous layers or particles from metallic surfaces (stainless steel, silicon wafer, aluminium alloy) [6,7].…”

Reduction of beam-divergence fluctuation for KTN optical beam deflector

“…O ptical beam deflection is indispensable for a wide range of applications such as microscopy, 1) laser marking, 2) optical 3D printing, 3) laser cleaning of rust, 4) optical coherence tomography, 5) eyeglasses for the visually impaired, 6) light detection and ranging, 7) and satellite communication systems. 8) Mechanical deflectors such as galvano mirrors and polygon mirrors have been widely used and can deflect an optical beam on the order of 1 rad, 9) but typically, the response speed is limited to a maximum of approximately ten kHz.…”
