Dynamic Control of Collapse in a Vortex Airy Beam
Here we study systematically the self-focusing dynamics and collapse of vortex Airy optical beams in a Kerr medium. The collapse is suppressed compared to a non-vortex Airy beam in a Kerr medium due to the existence of vortex fields. The locations of collapse depend sensitively on the initial power, vortex order, and modulation parameters. The collapse may occur in a position where the initial ...
متن کاملSimulation of an Airy Beam with Optical Vortex under Fractional Fourier Transforms
First, this study obtained the fields of an Airy beam (AiB) with optical vortex (OV) for a Fourier transform (FT) system and a fractional Fourier transform (fractional FT) system; thereafter, their intensity and phase patterns were simulated numerically. The splitting on each line of the phase pattern indicates the position of an OV. The results show that the OV position will change when the po...
متن کاملNonlinear beam steering by fractional vortex dipoles
Propagation of optical beams in nonlinear media NLM has been a subject of continuing interest for more than 4 decades due to the possibility for creation of reconfigurable waveguides through the intensity-dependent refractive index change 1,2 . Such optically induced waveguides can guide weak signal beams and pulses 3,4 , which motivates the investigation of novel techniques for manipulation of...
متن کاملAiry beam laser.
A method to design lasers that emit an arbitrary beam profile is studied. In these lasers, output-coupling is performed by a diffraction grating that imposes a phase and amplitude distribution onto the diffracted light. A solid-state laser emitting beams with a two-dimensional Airy intensity profile is demonstrated both theoretically and experimentally. In this case, the diffraction grating add...
متن کاملAiry beam optical parametric oscillator
Airy beam, a non-diffracting waveform, has peculiar properties of self-healing and self-acceleration. Due to such unique properties, the Airy beam finds many applications including curved plasma wave-guiding, micro-particle manipulation, optically mediated particle clearing, long distance communication, and nonlinear frequency conversion. However, many of these applications including laser mach...
