“…[9,10] The concept of charged-particle acceleration was originally proposed by Tajima and Dawson. Lin et al [15] have shown that the compression of the low intensity pulse by the plasmas might be a possible way to excite large amplitude wakefield. By the nonlinearities in response of the plasma to the pondermotive force, Kingham et al [12] have shown that the wakefield can be enhanced.…”

“…Sprangle et al [14] have shown that tapered plasma channels have been proposed to achieve greater electron acceleration in the laser wakefield mechanism. Lin et al [15] have shown that the compression of the low intensity pulse by the plasmas might be a possible way to excite large amplitude wakefield. Later, by Aossey et al [16] such type of wakefield was observed in three-component plasma.…”

The process of electron acceleration by both Bessel-Gaussian (BG) and Gaussian (G) laser pulses has been investigated comparatively in a homogeneous plasma. Starting with the hydrodynamics fluid and the Maxwell's equations, the three corresponding equations could be acquired which allow us to evaluate electron density perturbations (n ′ e ), wakefield (E w ) and electron energy-gain (ΔW) respectively for both pulses. Here, the pulse duration and the electron plasma period are taken the same, and by utilizing the perturbation theory the proposed equations have been solved. The analytical results show that the wakefield which leads to electron acceleration, depends on pulse intensity (I), pulse length (L), pulse wavelength ( ) and plasma density (n). Furthermore, by comparing the outcomes, the BG pulse is found to be most suitable for wakefield excitation. The pertinent electron could be accelerated up to 90 MeV if I = 4 × 10 21 W/m 2 , L = 20 μm and n = 5.318 × 10 24 m −3 . Our results are in a good agreement with experimental data reported in literature.

“…It has been an interesting subject for the both experimental and theoretical researches. Also the important industrial and medicinal applications should be enumerated [4]. The ponderomotive force of a short, ultrahigh intensity laser pulse, which is proportional to the negative gradient of the laser intensity, excites the plasma waves assuming the laser pulse maintains its shape.…”

We have conducted particle-in-cell (PIC) simulations of a linearly polarized intensive laser pulse with two different envelopes propagating through a homogeneous fully ionized cold plasma. It is shown that the amplitude of the wake field depends on laser wavelength, pulse duration, electron number density and envelope shape. We have also simulated the effect of applying a longitudinal magnetic field on the wake field excitation process. It is observed that magnetic field enhances the wake field and increases its intensity in all cases. Our results are in agreement with the analytical results presented by Askari and Shahidani [Opt. Laser Technol. 45, 613-619 (2013)] and can help choosing the optimum values of affecting laser and plasma parameters in order to reach high accelerating wake electric fields.keywords: laser pulse, wake field excitation, particle-in-cell (PIC), magnetized plasma pacS: 02.60.
