We experimentally probed the nonlinear optical response of aqueous nano-colloidal suspensions to provide a test of the theoretical approaches that have been proposed for the nonlinearity, namely an exponential model, an artificial Kerr medium, and a non-ideal gas model. The best agreement with experiment is found using the non-ideal gas model for the colloidal suspension which in turn can be used to infer values for the second virial coefficient of the medium and the nonlinear coefficients.

  12. “Critical collapse beyond a self-focusing power occurs for the case sd = 4, where s is the order of the nonlinearity, s = 2 for a Kerr medium, and d the number of transverse dimensions. Super-critical collapse occurs for sd>4 and tends to be much more abrupt spatially than critical collapse, see, for example, N. E. Kosmatov, V. F. Shvets, and V. E.
