【Abstract】 The nonlinear wave equation describing propagation of a femtosecond laser pulse with duration of several optical oscillation periods in a nonlinear fiber and the nonlinear fiber refractive index is derived by Maxwell’s equations. The solution of the nonlinear wave equation describing propagation of a femtosecond laser pulse with duration of several optical oscillation periods in a nonlinear fiber is presented. The physical process of the self phase modulation induced spectral broadening in a nonlinear fiber is studied detailedly. Condition of producing femtosecond laser pulse soliton in nonlinear fiber is studied.更多还原
