Stimulated Raman back-scattering of a laser in a magnetized plasma channel
- Centre for Energy Studies, Indian Institute of Technology, Delhi, New Delhi-110016 (India)
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 {approx_equal}a and Langmuir wave of extent b{approx_equal}(a{lambda}{sub D}){sup 1/2}<
