Decay instability of circularly polarized waves into circularly polarized and Langmuir waves in a magnetized plasma

Journal Article · · J. Plasma Phys., v. 11, pp. 99-109
OSTI ID:4334132
A study was made of a parametric instability in a magnetized plasma in which an electromagnetic pump wave of either right- or left-hand circular polarization decayed into a Langmuir wave and another circularly polarized wave, all with wave vectors colinear with the external magnetic field. The analysis was based on a multiple-time- scale perturbation expansion of the fluid equations, incorporating the effects of temperature, collisions, and the spatial variation of the pump wave. The threshold values of the pump field intensity required for instability and the growth rates above threshold were calculated. (auth)
