COLLISION DYNAMICS OF SUPER-GAUSSIAN BEAMS IN HIGHLY NONLOCAL MEDIA Introduction Nonlocal nonlinear media: liquid crystals, Bose-Einstein condensates Highly nonlocal: Response function width >> beam width Accessible solitons (AS): Simplified model for highly nonlocal media Studies on AS have revealed new phenomena not seen in local solitons Super-Gaussian (SG) Beams SG beams have narrow tails and flat-top peaks Contain less energy than Gaussian beams of same width SG parameter n controls edge sharpness and flattening of peak Mathematical Modeling Used nonlocal nonlinear Schrödinger equation (NNLSE) Gaussian response function models optical beam propagation Numerical Study of SG Beam Interactions Collision distance decreases with increasing n due to more oscillations SG beams recover original shape periodically during propagation Gaussian beam propagation more stable than SG beams Conclusion Collision distance between beams decreases with increasing SG n SG beams convert to Gaussian shape during propagation and recover periodically For longer interaction lengths, laser beam shape should be close to Gaussian in highly nonlocal media
