Ablation and laser-shock treatments
Laser surface processing and aqueous corrosion resistance.

In the pulse regime, and above a certain threshold power density f_th ≍ 10⁸ W/m², the laser-illuminated surface can vaporize and transform into a high-temperature, high-pressure ionized gas. This is known as a "plasma". These laser plasmas have a large number of potential applications in the field of very high intensities (megajoule lasers...), but can also be used for surface transformation, and in particular to improve electrochemical properties.

Among laser surface treatments involving vaporization phenomena, PLD (Pulsed Laser Deposition) treatments enable the production of thin deposits (< 0.5 μm) with controlled stoichiometry. In principle, a pulsed laser ablates a metal...
