Beryllium oxide contamination forms during laser processing of beryllium surfaces. Exposure to air causes oxide layer buildup, so it adheres tightly and covers evenly. Before cleaning, layer exhibits ceramic-like hardness, which resists standard removal methods.
In laser cleaning applications, unique patterns appear as thin films with irregular edges from heat zones. Contamination behaves specifically on beryllium because material toxicity adds handling risks, and oxide stability demands precise energy control. So, removal challenges arise from potential substrate damage during ablation.
After treatment, surface achieves cleanliness, but residue traces persist in cracks. Process removes most contamination effectively, as scans show reduced coverage. Observations indicate that intervals in laser pulses prevent re-oxidation, so outcomes improve uniformity on samples.
