Filamentation instability of an upper hybrid laser radiation propagating in a magnetoplasma

Presents an investigation of the filamentation instability of an upper hybrid laser radiation propagating in a magnetoplasma. The non-uniformity of the pump wave causes the redistribution of the electrons in the plasma. This modified density distribution is responsible for the self-focusing of the main beam. The spatial and temporal growth rates of filamentation instability increase with an increase in the magnetic field. For uniform plane waves, the spatial and temporal growth rates increase with an increase in beam power, but for gaussian beams, the growth rates are an oscillatory/decreasing/increasing function of the distance of propagation inside the plasma.
