Abstract
- In this paper, the effect of the wiggler magnetic field strength on the self-focusing of an intense laser pulse propagating through a magnetized non-Maxwellian plasma is studied. By using a relativistic fluid model, a non-linear equation describing the spot-size of the laser pulse for right- and left-hand polarizations has been derived. The evaluation of the spot-size in the self-focusing of laser pulse with the respect to the kind of polarization is investigated. Besides, the effects of wiggler magnetic field and a non-Maxwellian distribution of charge density on the evolution of the laser spot-size have been discussed. The results show that in the right-hand polarization, the existence of superthermal particles and wiggler magnetized field simultaneously cause improvement in the self-focusing quality. In addition, for the left-hand polarization, the self-focusing in the presence of wiggler field increases with an increase in the ki. Furthermore, the self-focusing decreases with an increase in the wiggler amplitudes for the left-hand polarization. Moreover, it is observed that an increase in the normalized laser frequency leads to an increase in the variation in the laser spot-size, and then the laser pulse becomes more focused.
