The effects of circularly polarized laser pulse on generated electron nano-bunches in oscillating mirror model

Abstract

The effects of the polarized incident laser pulse on the electrons of the plasma surface and on the reflected pulse in the relativistic laser-plasma interaction is investigated. Based on the relativistic oscillating mirror and totally reflecting oscillating mirror (TROM) regimes, the interaction of the intense polarized laser pulses with over-dense plasma is considered. Based on the effect of ponderomotive force on the characteristic of generated electron nano-bunches, considerable increasing in the localization and charges of nano-bunches are realized. It is found that the circularly polarized laser pulse have N e /N cr of 1500 which is almost two and seven times more than the amounts for P-polarized and S-polarized, respectively.

The Effects of Ripple Characteristics on the Simultaneous Relativistic-Ponderomotive Self-Focusing

“…The recent advances in the ultra-short intense lasers and their interaction with plasma have triggered important activities such as laser-driven fusion and monoenergy electron beams [1,2]. The mono-energetic electron beams, which are produced in laser-plasma accelerators are the source of important electromagnetic radiations such as X and gamma rays [3], ultra-short attosecond pulses [4], and terahertz radiation [5]. In the above mentioned applications, as well as all applications of relativistic laser-plasma interaction, the self-focusing phenomena plays an important role, which must be taken into account carefully.…”

The Effect of Chirped Intense Femtosecond Laser Pulses on the Argon Cluster

“…Optimization and control of this new source of energetic particles with different applications is a subject of current significance which can be modified by unique attractive techniques. One of the efficient attractive methods, interaction of intense laser pulses with large atomic clusters, has opened up several areas of laser plasma science such as electron and ion accelerators [15][16][17], table-top neutron sources [18], plasma waveguides [19] and X-ray sources [20][21][22]. Simulation of this interaction is not only scientifically very interesting but also has a wide range of applications.…”
