Abstract Non-Gaussian beam profiles such as Bessel or an-
nular beams enable novel approaches to modifying materials
through laser-based processing. In this review paper, proper-
ties, generation methods and emerging applications for non-
conventional beam shapes are discussed, including Bessel, an-
nular, and vortex beams. These intensity profiles have important
implications in a number of technologically relevant areas includ-
ing deep-hole drilling, photopolymerization and nanopatterning,
and introduce a new dimension for materials optimization and
fundamental studies of laser-matter interactions.
