“…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.

Under the influence of wiggler magnetic field, the phenomenon of second harmonic generation at the metal-semiconductor interface, induced by surface plasma wave (SPW) has been investigated. Metals like Cu, Ag and Al, each with a thin layer of n-InSb over it, are considered for our study.Laser light is incident on metal layered on glass prism in attenuated total reflection Kretschmann configuration (ATR) which generates SPW. The SPW further interacts nonlinearly with the electrons of n-type semiconductor layered over the metal, leading to second harmonic generation (SHG). The presence of an external wiggler magnetic field makes the process resonant and helps in phase matching. Relatively more enhancement in the amplitude of the second harmonic is observed for Cu-InSb as compared to Ag-InSb and Al-InSb. Numerical analysis shows that the enhancement in the amplitude of SHG increases with the wiggler magnetic field.

“…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.
