| Abstract: | We present experimental results on the evolution of ring dark solitary waves generated by computer-synthesized holograms. The data obtained and the detailed comparative numerical simulations show that this approach ensures reproduction of the correct intensity and phase portrait of the dark wave at the entrance of the nonlinear medium. The transverse dynamics at both even and odd initial conditions is studied and compared with the theory and simulations. Received: 24 June 1996 |
