TL;DR: In this article, the potential of ultrashort laser pulses to localize energy at metallic surfaces, in our case aluminum, was evaluated using a pump-probe experiment with ultrafast laser irradiation.

TL;DR: In this article, a self-learning loop based on temporal shaping of the ultrafast laser pulses is proposed to control laser-induced phenomena for practical applications. But it is not shown that under particular excitation conditions involving modulated excitation, energy flow can be controlled and the material response can be guided to improve processing results.

TL;DR: In this article, the surface damage/ablation threshold and processing morphology for sapphire were investigated after single and multiple laser pulse irradiation at 800 nm in the picosecond and sub-picosecond duration range.

TL;DR: In this paper, a time-resolved phase-contrast microscopy is employed to visualize spatio-temporal thermal transients induced by tight focusing of a single Ti:sapphire fs-laser pulse into a solid dielectric sample.

TL;DR: In this paper, the authors show that sequential energy delivery with judiciously chosen pulse trains may induce softening of the material during the initial steps of excitation and change the energy coupling for the subsequent steps.
