Effect Of Evolution Of The Interaction Between Femtosecond Airy Pulse And Femtosecond Gauss Pulse With Higher-order Nonlinear Effect

The high order coupling nonlinear Schrodinger equation is satisfied with the femtosecond Airy pulse,when only the Third-order dispersion effect?Self-steepening effect?Intrapulse Stimulated Raman scattering effect exist,as same time Self-steepening effect and Intrapulse Stimulated Raman scattering effect also another three exist,useing distribution Fourier transform and MATLA numerical simulation interact with the evolution of the femtosecond Airy pulse transmission in the fiber.The results show,Negative Third-order dispersion effect will accelerate penetration of the wave packet hased femtosecond pulses which can be transmitted over longer distances,positive Third-order dispersion effect will slow down the transmission of femtosecond pulses and the shock pulse will be transferred from the leading edge to the trailing edge if the is large enough.Self-steepening effect generated femtosecond pulse time-domain displacement by Soliton phenomenon form,Intrapulse Stimulated Raman effect will result in a longer wavelength side of the pulse generating Raman Self-frequency shift that femtosecond pulse energy can be transferred from the leading edge to the trailing edge.Both Intrapulse Stimulated Raman effect and Self-steepening effect exist simultaneously that result in femtosecond pulse generation time-domain displacement and the energy pulse at the leading edge will be transferred to the trailing edge.Self-bending characteristic and Self-acceleration features of the interaction of femtosecond Airy pulses result from the combined effect of the three simultaneous existence.
