ABSTRACT
We report new findings that relate to rapid maskless laser etching of steel and stainless steel in neutral solutions of sodium chloride, sodium nitrate, and potassium sulfate. Etch rates have been determined as a function of laser power, laser on-time, and solution concentration. The morphology of laser-etched holes obtained in these solutions was compared with holes obtained in pure water. Results indicate that some controlled melting occurs under certain laser conditions in addition to the metal dissolution process induced by the locally intense heat of the laser beam.

    Ablation rates of aluminum and stainless steel are studied as a function of fluence, hole depth, pulse duration and ambient pressure (air vs vacuum). We find a weak rate dependence on pulse duration from 150 fs to 500 ps, and a strong rate dependence on hole depth due to surface roughness....
