Abstract

The invention relates to a system (10) for treating a target (Tar) by laser shock under confinement in a liquid (Liq), the system comprising a pulsed laser generating a beam (B) having a pulse duration of between 1 ns and 30 ns and a wavelength, a concentrating optical device (COD) having a focal length and configured to concentrate the beam (B) on the surface (St) of the target (Tar), the laser beam (B) incident on the concentrating device having a diameter (D), a tank (TK) filled with said liquid (Liq) having a refractive index n, a desired value of the diameter (D) of the beam on a surface (St) of the target being predetermined and noted Dst, a thickness (e) of liquid (Liq) through which the beam (B) passes before reaching the surface (St) of the target (Tar) being chosen so that a laser intensity on the surface of the liquid (Liq) is less than or equal to a laser intensity on the surface of the target (Tar) divided by 2.
