The generation of wakefields in near-critical density plasma by a short
laser pulse is considered. The equations describing the plasma response to
the acting laser pulse and the Hamiltonian of an electron in the wakefield
are derived by using the Hamilton-Jacobi equation for the cases of and w< c (c is the speed of light). The
equations are solved analytically in two cases for a square-shaped laser
pulse. The plasma potential inside the laser pulse and the wakefield
potential excited by the laser pulse are obtained. The optimal length of the
driving laser pulse and the wavelength of the wake are expressed by the
group velocity.
