A laser source has two or more laser units (LA1, LA2) and coupling means for coupling the laser beams from each unit so as to deliver a resulting beam for treating a surface. Concurrently with the laser surface treatment, the characteristics of the laser beam (FLA1, FLA2) from each unit (LA1, LA2) are adjusted to produce a resulting laser beam with a time profile of energy optimally adapted to said laser surface treatment. Homogenising means (HO) homogenise the energy distribution of the resulting laser beam, so that the energy and spatial distribution of said resulting laser beam are concurrently adapted for the selected surface treatment.
La source laser comprend au moins deux modules laser (LA1, LA2) ainsi que des moyens de couplage propres à coupler les faisceaux laser issus de chaque module pour délivrer un faisceau laser résultant destiné au traitement d'une surface. En combinaison avec le traitement de surfaces par laser, il est prévu d'ajuster les caractéristiques des faisceaux laser (FLA1, FLA2) issus de chaque module (LA1, LA2) pour obtenir un faisceau laser résultant avec un profil temporel de puissance énergétique adapté de façon optimale audit traitement de surface par laser. Des moyens homogénéiseurs (HO) homogénéisent la répartition énergétique dudit faisceau laser résultant, ce qui permet d'adapter, en combinaison, la répartition spatiale et énergétique dudit faisceau laser résultant au traitement de surface choisi.
