Abstract- In this paper ,in order to achieve a short attosecond pulse, the effects of nonlinear time dependent phase, "chirp", on a three color laser field  has been studied. So, with the propuse of producing high order harmonics for a three color laser field, we have solved the time dependant 1D Schrodinger equation for single Helium atom . Result of simulation has shown that applying nonlinear chirp to a three color laser field has caused the extension of plateau and The cutoff frequency in the harmonic spectra and as a result we have succeed to produce a short 79 attosecond pulse.

Keywords: attosecond, cut off, nonlinear chirp, plateau
