Title: Effect of nonlinear chirped Gaussian laser pulse on plasma wake field generation

Abstract

An ultrashort laser pulse propagating in plasma can excite a nonlinear plasma wake field which can accelerate charged particles up to GeV energies within a compact space compared to the conventional accelerator devices. In this paper, the effect of different kinds of nonlinear chirped Gaussian laser pulse on wake field generation is investigated. The numerical analysis of our results depicts that the excitation of plasma wave with large and highly amplitude can be accomplished by nonlinear chirped pulses. The maximum amplitude of excited wake in nonlinear chirped pulse is approximately three times more than that of linear chirped pulse. In order to achieve high wake field generation, chirp parameters and functions should be set to optimal values.

  • One-dimensional nonlinear analysis of wake-field generation and electron bunch acceleration by a chirped laser pulse were investigated numerically. It was found that the optimum linear chirp parameter leads to the wake-field amplitude increase by one order of magnitude and accordingly the acceleration gradient. In our external injection scheme, electrons were accelerated using the initial energy of 100 KeV (gamma{sub in}=1.2). When the pulse passes through the electron bunch most part of the electrons trapped in the first cycle of the laser wake-field and accelerate to about 1 GeV in 1.8 mm. We concluded that the expensive electron preacceleration mechanism couldmore » be omitted in a laser-aided electron acceleration scheme.« less
  • The results of a two-dimensional particle-in-cell simulation and of an analytical description of the propagation in an underdense plasma of a short, relativistically intense, laser pulse are presented. Self-focusing is proven in an ultrarelativistic regime for moderately long pulses. Pulses shorter than the plasma wavelength, but wider than it, excite a wake wave with a regular electric field. The electron density in the wake has a horseshoe'' shape and focuses a long pulse locally. The excitation of stimulated Raman backward scattering is observed.
  • Magnetic field generation in the plasma wake of a relativisticly intense short pulse is studied, both analytically and by PIC-code simulation. We show that the magnetic field scales like (m{omega}{sub p}c/e)dI{sub L}/dr{sub perpendicular} in this case, different from (m{omega}{sub p}c/e)dI{sub L}{sup 2}/dr{sub perpendicular} for the low intensity case. The magnetic field profiles are calculated both for {beta}=1 and {beta}<1, which are found to be different in these two cases; here {beta} is the normalized phase velocity of the wake plasma wave.
  • We propose a method to generate an isolated attosecond (as) pulse in combination with a chirped fundamental laser field (5 fs, 800 nm) and a subharmonic laser field (12 fs, 1600 nm). It is shown that, for the case of the chirped parameter {beta}=0.25, not only is the efficiency of the extended harmonics enhanced, but also an ultrabroad supercontinuum is formed in the second plateau. For the case of {beta}=0.65, an ultrabroad supercontinuum spectrum with the width of about 1670 eV can be observed. Furthermore, due to the introduction of chirped pulse, the short quantum trajectory is enhanced, and themore » long one is suppressed. By superposing a properly selected range of the harmonic spectrum in the continuum region, an intense isolated 38-as pulse is generated.« less
  • We theoretically demonstrate the generation of a high-order harmonic and isolated attosecond pulse in an orthogonally polarized laser field, which is synthesized by an 800-nm chirped laser pulse and an 800-nm chirp-free laser pulse. Owing to the instantaneous frequency increasingly reducing close to the center of the driving pulse, the extreme ultraviolet supercontinuum for the chirped synthesized field is even broader than that for an orthogonal chirp-free two-color laser field. It is found that the broadband supercontinuum spectrum can be achieved for the driving pulse with ten and above optical cycles. After phase compensation an isolated attosecond pulse with amore » duration of {approx}16 as is produced. Furthermore, the optimization of the chirping rate parameters is investigated to achieve cutoff extension and an isolated short attosecond pulse.« less
