Abstract

An optical vortex, [1, 2] exhibiting attractive features, such as an annular spatial profile in the far-field and an orbital angular momentum due to a phase singularity, has been attracting much attention. In particular, high-power optical vortex pulses can explore potentially various technologies, including super-resolution microscopes [3] and material processing.
