| Description: |
The parametric excitation of longitudinal waves in an infinite homogeneous plasma by a pump field E ( t ) = E 0 ( t ) sin (ω 0 t + φ( t )) is studied on the basis of the Vlasov equation, where the amplitude E 0 ( t ) and the phase φ( t ) are slowly varying compared with ω 0 periodic functions. Firstly it is assumed that ω 0 is much larger than the electron plasma frequency ω Le . In the second part the parametric instabilities are considered under the resonance condition ω 0 ≈ ω Le . In both parts the threshold fields for the excitation of the longitudinal waves and their growth rates are calculated. As an example these values are analysed for both a sequence of pump impulses and a phase‐moduated pump field. They are compared with the results received for a monochromatic pump field. |
