Notes:
A series of computer simulations is reported showing the generation of electromagnetic radiation by strong Langmuir turbulence. The simulations were carried out with a fully electromagnetic 2 1/2 -dimensional fluid code. The radiation process takes place in two stages that reflect the evolution of the electrostatic turbulence. During the first stage while the electrostatic turbulence is evolving from an initial linear wave packet into a planar soliton, the radiation is primarily at ωe. During the second stage when transverse instabilities lead to the collapse and dissipation of the solitons, 2ωe and ωe radiation are comparable, and 3ωe is also present. The radiation power at ω=2ωe is in good agreement with theoretical predictions for electromagnetic emissions by collapsing solitons.
