Laser drilling covers the production of precision holes in aerospace components using focused high-energy laser beams, encompassing percussion, trepanning, and helical drilling methods applied to superalloys, titanium, ceramics, and composite materials. The process is widely used for effusion and film-cooling holes in turbine blades and combustor liners, with Nd:YAG, CO₂, and ultrashort-pulse laser sources applied to achieve tight geometrical tolerances and controlled recast-layer characteristics.
