Erratum: “Nonlinear inverse bremsstrahlung absorption in laser-fusion plasma corona” [Phys. Plasmas <b>10</b>, 214 (2003)]

The nonlinear propagation of an ultraintense and ultrashort (UIUS) laser pulse in a metallic capillary is investigated using a classical model which takes into account the inverse bremsstrahlung absorption (IBA) in the formed plasma. The attenuation of the laser pulse due to the IBA in the plasma and to the laser energy dissipation in the metallic walls is shown. The guiding length and the twist of the laser pulse temporal envelope are presented for several values of the parameters of the plasma, the laser pulse and the metal. The numerical treatment shows that the guiding length increases when the pulse duration becomes shorter. This calculus shows also that in the case of moderate electronic densities, ne<1017m−3, the formed plasma has a negligible effect compared to that of the metallic walls.

In this paper, the Weibel instability, driven by the plasma temperature anisotropy, in the corona of high intense laser fusion plasma is studied. The unperturbed electronic distribution function, f , of the anisotropic corona is supposed to be a bi-Maxwellian. That T = T ⊥ ± W O , where W O = 1 4 m e v 2 O is the averaged electron quiver energy in the laser electric field. The first and the second anisotropies of f projected on the Legendre polynomials are calculated as a function of the scaling parameter, W O T ⊥. The Weibel instability parameters are explicitly calculated as a function of the scaling parameter. For typical parameters of the laser pulse and the fusion plasma, it has been shown that very unstable Weibel modes, γ 10 11 s −1 , can be excited in the corona.

“…Weibel instability is a micro-convective instability that corresponds to plasma characterized by temperature anisotropy. [1] In kinetic theory, described by a second distribution function developed on the Legendre polynomials in the space of velocities (energies), we have T ≈ ∫ E(V)F(V)d 3 V. Here, in the case of small temperature anisotropy, it can be written as: ΔT = T ∥ − T ⊥ ∼ ∫ E(V)F 2 V 2 dV. Temperature anisotropy can be generated in a plasma through different mechanisms, such as heat transport, expansion of plasma, and inverse Bremsstrahlung absorption (IBA).…”

In this work, we studied the relativistic Weibel instability (RWI) in magneto‐inertial fusion experiment (MIFE); for this, the basic equation in our model is the relativistic Fokker–Planck equation. We solve the dispersion relation of low frequency and deduce the growth rate of RWI. The main results obtained are that the IBA source alone is capable to reduce the RWI, and also the coupling between it and the external magnetic field contributes strongly to achieving a reduction of the RWI, it has been shown clearly that the relativistic effect under this conditions can be decrease the values of growth rate of WI.
