Keywords:Optical vortex, Orbital angular momentum, Structured light
To date, we have demonstrated the wavelength extension of optical vortex laser sources in the ultraviolet ~ terahertz region by employing both second order and third order nonlinear processes, and we have successfully developed continuous-wave or pulsed tunable optical vortex laser sources with versatile OAM states and moderate energy levels in a visible, near-infrared, and mid-infrared regions.
Such versatile vortex laser sources should open an avenue towards novel fundamental sciences and advanced technologies beyond conventional optical tweezers, light-matter interactions, telecommunications, biomedical imaging technologies, and micro-fabrications.
In this presentation, we report on a recent progress of wavelength versatile vortex laser sources based on solid-state laser and nonlinear frequency extension technologies. We also address the state of the art of optical vortex materials processing.
