“…The nonlinearity may, however, get saturated for some materials like semiconductor (CdS x Se 1 )-doped glass and organic polymers. [12][13][14][15] It is seen that chalcogenide glasses exhibit saturable nonlinearity and generate higher-order nonlinearity at a larger reducedphoton energy. 16,17) The existence of nonlinearity saturation has motivated several interesting works in the framework of both generalized and fractional NLS models.…”

We study the properties of an intense pulse propagating in dissipative nonlinear systems considering nonlinear dispersion within the framework of variational approach. We model the system by the so-called saturable cubic-quintic nonlinear Schrodinger equation including perturbing terms like two photon absorption, intra-pulse Raman scattering and dissipative losses. Introducing Rayleigh's dissipative function we derive a set of couple differential equations for the various parameters of the pulse. It is clearly demonstrated how the interplay among dispersion, saturable nonlinearity and dissipative losses affects intense-short pulse propagation in optical media.
