Ring dark solitary waves: Experiment versus theory

A. Dreischuh, D. Neshev, G. G. Paulus, F. Grasbon, H. Walther


Experimental results on optical ring dark solitary wave dynamics are presented, emphasizing the interplay between initial dark beam contrast, total phase shift, background-beam intensity, and saturation of the nonlinearity. The results are found to confirm qualitatively the existing analytical theory and are in agreement with the numerical simulations carried out
