PCT No. PCT/FR96/01060 Sec. 371 Date Jan. 22, 1998 Sec. 102(e) Date Jan. 22, 1998 PCT Filed Jul. 5, 1996 PCT Pub. No. WO97/07578 PCT Pub. Date Feb. 27, 1997A laser source has two or more laser units 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 from each unit are adjusted to produce a resulting laser beam with a time profile of energy optimally adapted to said laser surface treatment. Homogenizing means homogenize 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.
