Реферат: This invention concerns a method of laser processing comprising generating a laser beam (118) having, at different longitudinal positions in a propagation direction, first and second transverse beam profiles of energy density. The first transverse beam profile is different to the second transverse beam profile and is non-Gaussian. The method comprises carrying out a scan of the laser beam (118) across a working surface (104a), wherein, during the scan, the laser beam (118) and/or working surface (104a) is adjusted such that, for a first part of the scan, the first transverse beam profile is located at the working surface (104a) and, for a second part of the scan, the second transverse beam profile is located at the working surface (104a).
