Abstract

Laser-plasma accelerators are considered one of the new technologies to reach high energies. In this paper, while reviewing recent findings in the field of electron acceleration by laser pulse in a plasma channel, the mechanism of producing high-energy electrons in the interaction of femtosecond laser pulse with plasma is investigated and the amount of energy obtained in linear and non-linear interaction is estimated. Considering the density disturbances and the changes of the electric field of the wakefiled wave, it is shown that the energy of electrons decreases with the increaseing plasma density and increases with the increasing of plasma length and laser power. Also, changes in radius of the electron bubble and the number of accelerated electrons inside the bubble have been estimated at different plasma densities
