A device for subjecting to laser treatment articles, in particular articles chosen between sanitary products and components of said products, comprises a laser-beam source configured for applying to the articles a laser spot with a diameter of between 50 .mu.m and 2000 .mu.m. Preferentially, the laser spot has a wavelength of between 9.0 .mu.m and 11.0 .mu.m The control unit is configured to regulate jointly the power of the laser spot, the instantaneous relative speed of the laser spot with respect to the article treated, and the instantaneous diameter of the treatment laser spot.
