Ultrashort laser pulses can serve as fast probes to record instant events.The isolated attosecond pulses(IAPs)generated from high-order harmonic generation(HHG)have been shortened down to about 2 atomic units in time,...
In this study, the exact solutions for the propagation of pulses in optical fibers are obtained.Special values are given in the model used, and two nonlinear differential equations are obtained.Nonlinear equations are...
