    • Acccording to the present application, a device for subjecting to laser treatment articles (A) , in particular articles chosen between sanitary products and components of said products (A), comprises a laser-beam source (1) configured (2, 3) for applying to the articles (A) a laser spot with a diameter of between 50 um and 2000 um. Preferentially, the laser spot has a wavelength of between 9.0 um and 11.0 um and it is with the beam mode chosen between OO MODE, D MODE and Q MODE. In a preferred way, the laser source (1) generates a non-parallel beam and the optical distance between said source (1) and said deflectors (3) is variable for regulating the diameter of said laser beam. To convey the laser beam towards the articles (A) pressurized pipes are provided, as well as reflection systems (2) and deflection systems (3) . A system of movement (3, 9) is provided for producing a scanning movement between the laser spot and the articles (A), as well as a real-time control unit (4), configured for regulating the power associated to the laser spot as a function of the instantaneous speed of the aforesaid relative movement, obtained preferentially via a conveyor (9), which feeds the articles in a direction (z), and at least one deflection unit (3), which imparts on the laser spot a movement of deflection with at least one component in a transverse direction (x) with respect to the direction (z) of advance of the articles (A).
