In this paper,a new way of generating the single attosecond pulses via Thomson scattering of linearly polarized Gaussi an beam propagating on solid surface is investigated.It is found that a single attosecond laser pulse is generated,which renders the appropriate strength elect rostatic field to the environment.The influence of the electrostatic fields with four different intens ities on the pulse of electrons at the half-waist position is studied.The results show that with the same paramete rs,namely,pulse radius is r₀=5,waist width is w₀=3,continuous cycle time is 200ms and the P=1 (l inear polarization),four different electrostatic fields can generate the attosecond pulses.But only when the Gaussian velocity of light intensity is 5and the intensity of electrostatic fie ld is E_s= 5×10－4,a single attosecond pulse is generated with a pulse width of 16as,stronger than that wit hout any other electrostatic field intensity with direction simplification.Therefore,it can be concluded that the single attosecond pulse can be generated by the interaction between the electrostatic f ield with Gaussian intensity of E_s= 5×10－4 and stationary sing le electron.
