We find bright and dark solitary wave solutions for the higher-order nonlinear Schrodinger equation with cubic-quintic-septic terms adopting the ansatz solution of Li et al. [Li Z, Li L, Tian H, Zhou G. Phys. New types of solitary wave solutions for the higher-order nonlinear Schrodinger equation. Phys Rev Lett 2000;84(18):4096-99.] which may describe propagation of pulses upto the order of 10 fs in a non-Kerr media. In this context, we have taken into account both the Raman and the self-steepening effect. All the solitary wave parameters and the parametric conditions for the solitary wave solutions are worked out. (C) 2009 Elsevier B.V. All rights reserved.
