Abstract

A study is made of the generation of electromagnetic waves during the merging of two Langmuir plasmons in a hot plasma with a magnetic field. It is shown that the frequency of Langmuir plasmons can vary in the range from 0.8 to 1.1 of the electron Langmuir frequency. The spectrum and polarization of the emitted electromagnetic radiation are analyzed. It is found that the thermal motion of plasma particles may lead to the generation of electromagnetic waves in the frequency range from 1.6 to 2.2 of the electron Langmuir frequency. In a plasma with an isotropic Langmuir turbulence spectrum, the degree of circular polarization of the emitted radiation can amount to 50%.
