“…The different intensity profiles of laser beams are also important in their propagation through plasmas [4]. It is well known that by applying external magnetic field, self-focusing of the laser beam propagating through plasma can be changed, which have wide range of applications such as harmonic generation [5,6], laser wakefield acceleration [7,8], generation of THz radiation [9,10], etc.…”

In this paper, the propagation of Gaussian laser beam in underdense and magnetized plasma has been studied. The effect of oblique external magnetic field on self-focusing of laser is specifically explored. An envelope equation governing dependence of beam-width parameter with dimensionless distance of propagation of laser is derived by adopting parabolic equation approach under WKB and paraxial approximations. It is found that increasing the angle between the laser beam magnetic field and external magnetic field decreases the self-focusing of laser propagating through plasma.

“…When a constant external magnetic field is applied to the plasma, it affects the self-focusing of laser beams [5]. Such magnetization of plasma leads to wide-ranging applications such as harmonic generation [6,7], laser wakefield acceleration [8,9], generation of THz radiation [10], etc.…”

A well established parabolic equation approach to study the evolution of self-focusing of Gaussian laser beam in underdense, magnetized plasma has been presented. The uniform external magnetic field is assumed to be applied along (forward) as well as opposite (reverse) to the direction of propagation of laser beam. The nonlinear differential equation governing dimensionless beam-width parameter is derived under WKB and paraxial approximations. It is observed that forward (reverse) magnetic field increases (decreases) the self-focusing of Gaussian laser beam as compared to the unmagnetized case of reference.

“…Shibu and Tripathi [27] have studied phasematched third harmonic generation of a laser beam propagating through a plasma channel and showed that the presence of a background density perturbation can account for phase-matching. Salih et al [28] have studied the secondharmonic generation of a Gaussian laser beam in a self created magnetized plasma channel. Rax et al [29] demonstrated that when an intense plane polarized laser pulse interacts with a plasma, the relativistic nonlinearities induce third harmonic radiation.…”

Third harmonic generation due to linearly polarized Gaussian laser pulse propagating through quantum plasma immersed in transverse wiggler magnetic field is studied using the quantum hydrodynamic (QHD)model. The effects associated with the Fermi pressure, the Bohm potential and the electron spin have been taken into account.Wiggler magnetic field plays both a dynamic role in producing the harmonic current and a kinematical role in ensuring phase-matching. It is shown that the harmonic radiation attain the maximum valueat an instant when the phase matching is satisfied and thereafter decreases at later duration of laser pulse. The quantum effects also add to harmonic generation in the phase-matched case.
