Robust Two-Dimensional Spatial Solitons in Liquid Carbon Disulfide

The excitation of near-infrared (2 + 1)D solitons in liquid carbon disulfide is demonstrated due to the simultaneous contribution of the third-and fifth-order susceptibilities. Solitons propagating free from diffraction for more than 10 Rayleigh lengths although damped, were observed to support the proposed soliton behavior. Numerical calculations using a nonlinear Schrodinger-type equation were also performed. DOI: 10.1103/PhysRevLett.110.013901
