A wide spectral band laser pulse generating device capable of covering a spectrum formed of given wavelengths is provided, including: a monochromatic laser light source whose intensity is adjustable; non-linear optical means, a photonic crystal or a microstructured optical fiber for example, for carrying out spectral widening of the wave emitted by the light source; the light source and the non-linear optical means are configured and arranged so as to create a white supercontinuum whose continuous spectrum contains the wavelengths considered. The invention relates to the general field of the analysis of the composition of material specimens, and in particular to laser tomographic atom probes.
