Abstract

In this study we report on the ablation of steel using femtosecond double-pulse trains. Double-pulse trains with pulse-to-pulse separations between 1 ps and 1 ns were used to machine micro-channels in a steel sample. The depths of the laser-ablated channels were measured to characterize the efficiency of the ablation process. Results show that using a double-pulse train with an optimal separation time dramatically increases the ablation depth and does not deposit unwanted material that may require additional post-processing of the machined surface.
