Generation of high-quality terahertz OAM mode based on soft-aperture difference frequency generation
Katsuhiko Miyamoto, Kazuki Sano, Takahiro Miyakawa +4
We demonstrate the generation of high-quality tunable terahertz (THz) vortices in an eigenmode by employing soft-aperture difference frequency generation of a vortex output and a G…
Generation of coupled orbital angular momentum modes from an optical vortex parametric laser source
Roukuya Mamuti, Shunsuke Goto, Katsuhiko Miyamoto +1
We report on the generation of flower (wheel) modes, which manifest coupled orbital angular momentum (OAM) modes, from a vortex pumped optical parametric oscillator simply by emplo…
Optical vortex-induced forward mass transfer: Manifestation of helical trajectory of optical vortex
Ryosuke Nakamura, Haruki Kawaguchi, Muneaki Iwata +6
The orbital angular momentum of an optical vortex field is found to twist high viscosity donor material to form a micron-scale 'spin jet'. This unique phenomenon manifests the heli…
