“…In ref [17] the present work has the aim to investigate the non-relativistic Weibel instability induced by inverse bremsstrahlung in laser fusion plasma, where the effect of the self-generated magnetic field is induced. Specifically, we have considered the generated static magnetic field effect on the inverse bremsstrahlung absorption.…”

In this work, have put forward a philosophy of the Weibel instability in laser fusion plasma; these instabilities generated by several mechanisms, namely: the heat transport, the expansion of the plasma and the inverse bremsstrahlung absorption (IB). Several research papers have been presented as well as theoretical models for the relaxation and stability of these modes, which are considered to be very flammable and peaceful on the interaction yield between lasers and plasma. To resolve these modes must be combined with the magnetic field. The stabilization effect due to the coupling of the self-generated magnetic field by Weibel instability with the laser wave field is explicitly showed in recently paper. In these studies, the relativistic and non-relativistic or linear and non-linear effects are taken into account here; the basic equation is the Fokker-Planck (F-P) or Vlasov equation. The best result is that the coupling of self-generated magnetic field with the laser wave causes a stabilizing effect of excited Weibel modes in the all states. Found a decrease in the spectral range of Weibel unstable modes. This decreasing is accompanied by a reduction of orders in the growth rate of instability or even stabilization of these modes. It has been shown that the previous analysis of the Weibel instability due to IB have overestimated the values of the generated magnetic fields.

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.

We study the Weibel instability (WI) in plasma heated by a laser pulse in the relativistic regime under Jüttner-Maxwell distribution function (relativistic Maxwellian), for this the basic equation in our model is the relativistic Vlasov equation .we solve the dispersion relation of low frequency and deduce the growth rate of WI. The main obtained result is that the choice of plasma density, quick scale time and electronic temperature can be stabilized the value of growth rate of WI; when shown clearly that the relativistic effect sureties the spectrum of growth rate of WI.
