Emergence of order, self-organization and instabilities in a 1-D array of solitons

The paper reports on the generation of spatial solitons with carbon disulfide (CS_2) as the nonlinear material, which has a critical power of 190 kW for the laser wavelength of 800 nm. A 150-femtosecond pulse with a maximum energy of 1 mJ is also used. Each pulse from the laser is split into pump and probe pulses. The pump pulse is focused into a line (using a cylindrical lens) at the entrance face of a 10 mm glass cell filled with CS_2.
