This work focuses on the propagation behaviors and stabilities of solitons of a nonlinear
Schrödinger equation with temporally inhomogeneous dispersion, cubic–quintic–septic …

We report an observation of spatial solitons in a medium managed to present fifth-seventh
(focusing-defocusing) refractive nonlinearities with suppressed third-order nonlinearity …

A class of derivative nonlinear Schrödinger equation with cubic-quintic-septic-nonic
nonlinear terms describing the propagation of ultrashort optical pulses through a nonlinear …

While filaments are generally interpreted as a dynamic balance between Kerr focusing and
plasma defocusing, the role of the higher-order Kerr effect (HOKE) is actively debated as a …

We directly measure the nonlinear optical response in argon and nitrogen in a thin gas
target to laser intensities near the ionization threshold. No instantaneous negative nonlinear …

A large family of analytical solitary wave solutions to the generalized nonautonomous cubic-
quintic nonlinear Schrödinger equation with time-and space-dependent distributed …

A generalized nonlinear Schrödinger equation with polynomial Kerr nonlinearity and non-
Kerr terms of an arbitrarily higher order is investigated. This model can be applied to the …

We consider a higher-order nonlinear Schrödinger equation that models the evolution of
ultrashort optical pulses in nonlinear media exhibiting nonlinearities up to the ninth order …

Calculations are performed of the phase shift caused by the spatial modulation in the
plasma density due to interference between a strong pump pulse and a weak probe pulse. It …

The nonlinear coefficients, n 4, of the time-dependent refractive index for argon are
calculated in the non-resonant optical regime. Second-order polynomial fitting of DC-Kerr, γ …
