Absolute Parametric Instability of an Inhomogeneous Plasma,
Abstract
A plasma which is subjected to the influence of a powerful pumping wave is unstable relative to the build up of plasma high-frequency electronic waves (plasmons); this is caused by the decay of the pumping wave into two plasmons. The article that follows studies the effect of a spatial inhomogeneous plasma on this kind of parametric instability. It has been shown that consideration of the spatial inhomogeneity of the plasma produces two effects: in the first place, plasma inhomogeneity leads to a considerable increase in the threshold of the pumping wave's decay into two high-frequency electron waves and, secondly, are enclosed in the plasma; this corresponds to absolute instability.
