In this study, the effects of ultrashort laser pulse shape for the laser-matter interaction have been considered. Three
different pulse shapes, Gaussian, Super-Gaussian, and Cosine-Squared, are used to calculate the dipole spectrum
of the single atom by considering the Lewenstein model. The ultrashort laser pulse shapes are presented, and it has
been found that the super-Gaussian laser pulse, which has a spiky and strong tail, has been more effective in
transferring energy to the electron. The electron is excited and gains kinetic energy under the ultrashort laser pulse.
The laser pulse-electron interaction affects the ground state wave function and the returning electron wave packet.
The optimum dipole spectrum, which is extended to higher photon energies, has been obtained under the Super-
Gaussian pulse shape.
