Abstract

The invention relates to a method for improving the reflectivity of an aluminium or aluminium alloy sheet or web. It comprises the irradiation of the surface of the sheet or web by means of a ray emitted by an excimer laser, in an homogeneous way on the treated surface and perpendicularly to the latter, with one or a plurality of pulses having an energy density comprised between 2 and 8 J/cm<2> (for a wavelength of a laser beam of 308 nm). The mean roughness of the surface is reduced by at least 50 % and the reflectivity is increased by at least 25 %.
