A Gaussian laser beam, propagating as an eigenmode through a low density plasma channel in the presence of an axial magnetic field, undergoes stimulated Raman back scattering, producing an upper hybrid wave and a radially localized electromagnetic sideband wave. The channel may be self created by the laser due to ponderomotive force or by a pre-pulse. The radial width of sideband is ≈a and Langmuir wave of extent b≈(aλD)1/2<

    Focusing of intense laser beams by a thin magnetized plasma slab is investigated. A thin plasma slab is used as an optical element. The focal length is the distance between the plasma lens and the laser beam focus point. The external magnetic field is applied along the direction of the laser...

    In this paper, evolution of the spot size of an intense laser beam propagating in axially magnetized, cold, underdense plasma has been studied. The effect of longitudinal magnetization on the laser spot for a left as well as a right circularly polarized laser beam has been considered. Critical...

    The output power of any laser system is limited by the power that any of its individual components can withstand without being destroyed. This increases the size, complexity and cost of next-generation lasers built using conventional optical-gain media. But by using a plasma, which is impervious...

    We propose a new device for detecting high-frequency gravitational waves (HFGWs) in the GHz band, which consists of a high-quality-factor open microwave cavity and a Gaussian beam (GB) passing through a static magnetic field in free space. Essentially this effect is an inverse Gertsenshtein...

    A time-resolved study is presented of stimulated Raman backscatter (B-SRS) produced in a large-scale-length preformed plasma in an intense laser pulse. The first direct experimental results are presented to (i) show that the B-SRS is generated predominantly in laser filaments and (ii) provide a...
