Abstract

Laser-created sub-surface features inside transparent materials (e.g. glass) are used for crafting three-dimensional artworks and memorabilia that are displayed at home and offices. Creating sub-surface features in opaque metals by a laser beam was believed not feasible due to the high absorption coefficients of the metallic materials. Our previous report [1] for the first time demonstrated direct patterning in the sub-surface of stainless steel by realizing a series of microcavities to form a predesigned pattern. In this paper, we report our latest study of the effect of laser pulse duration on microcavity formation. Results are presented for an austenite stainless steel plate interacting with single laser pulses with durations of 0.5 ms and 1 ms, using a Nd:YAG laser.
