Diamond-Like Carbon Removal

Diamond-coating contamination poses removal challenges in laser cleaning. Contaminants form unique patterns on diamond surfaces because heat resistance causes uneven buildup during exposure. Layer adheres strongly, so laser pulses struggle to detach it without damaging coating. After initial cleaning, residue persists on edges. Process targets inorganic layers effectively, yet material hardness demands precise control. Contamination exhibits dense attachment, and removal requires adjusted wavelengths for safety. In observations, patterns vary by substrate, so intervals prevent overheating. Buildup is detected early on polished areas. Treatment removes layers gradually, and surface regains uniformity afterward.
