Optical vortex laser, showing an annular intensity profile and orbital angular momentum owing to a
spiral wavefront, has a potential to be applied to various fields such as optical manipulation, super
resolution microscopy, and optical telecommunication. Recently, we and our co-workers have
discovered that optical vortex lasers enable us to provide chiral structured materials on nano-scale. In
this paper, we review a recent progress of high power optical vortex lasers based on a fi ber and solidstate
laser technologies, and we also address physical properties of chiral structured materials formed by
irradiation of optical vortex lasers.
