We propose a method for opto-thermophoretic trapping with a 2 µm Tm-doped fiber laser. The infrared continuous-wave laser beam is directly and strongly absorbed by water solution, and some local temperature gradient is generated around a focus. The

Optical vortices with a ring-shaped spatial form and an orbital angular momentum (OAM) of Ι ϕ [1], arising from their helical wavefronts characterized by an azimuthal phase, exp(iΙ ϕ ) (where Ι is an integer termed the topological charge), have
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 employing a pump source with a short temporal coherence time. This vortex o

We report on a tunable 2 μm optical vortex laser source formed of a periodically poled stoichiometric lithium tantalite (PPSLT) optical parametric oscillator with a singly-resonant cavity configuration. A milli-joule level vortex output was generate

We present an optical vortex parametric laser with an ultra-broadband tunability (665–2525 nm). Also, the topological charge of the vortex signal (idler) output is selectively switched in a range of +2 ~ 0 (+1 ~ −1).
