Nn. Rosanov et al., NUMERICAL SIMULATIONS OF INTERACTION OF BRIGHT SPATIAL SOLITONS IN MEDIUM WITH SATURABLE NONLINEARITY, Chaos, solitons and fractals, 4(8-9), 1994, pp. 1767-1782
We present numerical simulations of interaction of bright transversely
two-dimensional solitons with different topological indices in a homo
geneous transparent medium with saturable self-focusing nonlinearity o
f refraction index. We describe also the propagation and interaction o
f powerful light beams, including vortices, in such medium.
