Abstract: The subject of the invention is a process for obtaining a substrate provided on at least one portion of at least one of its sides with a coating, comprising a step of depositing said coating on said substrate, then a step of heat treatment of said coating using a pulsed or continuous laser radiation focused on said coating in the form of at least one laser line, the wavelength of which is within a range extending from 400 to 1500 nm, said heat treatment being such that a relative displacement movement is created between the substrate and the or each laser line, the speed of which is at least 3 meters per minute, the or each laser line having a beam quality factor (BPP) of at most 3 mm·mrad and, measured at the place where the or each laser line is focused on said coating, a linear power density divided by the square root of the duty cycle of at least 200 W/cm, a length of at least 20 mm and a width distribution along the or each line such that the mean width is at least 30 micrometers and the difference between the largest width and the smallest width is at most 15% of the value of the mean width.
