Abstract

The theory for third and higher harmonic plasma emission by the weak turbulence (or random phase) process L + T′→T (where L denotes a Langmuir wave, and T and T′ denote transverse waves) is developed. Kinematic constraints on the characteristics and growth lengths of waves participating in the wave processes are identified. The cases of L waves produced either directly by a streaming instability, or by the decay L→L′+S (S is an ion sound wave) of L waves generated by a streaming instability, are considered. Limits on the brightness temperature of the radiation are determined, and expressions for the growth rate and path-integrated wave temperatures are derived.
