Air particles move with the speed temperature dependent. Electrons do the same. S* |

S* you can do better than that, you just aren't being any fun now! I do my best. May be the Wiki is better: "The electron temperature of a plasma can be several orders of magnitude higher than the temperature of the neutral species or of the ions. This is a result of two facts. Firstly, many plasma sources heat the electrons more strongly than the ions. Secondly, atoms and ions are much heavier than electrons, and energy transfer in a two-body collision is much more efficient if the masses are similar." You know: The Sun produces the plasma (it rotate with the Sun) and the plasma is a medium for the longitudinal electric waves (Tesla - the father of the radio). Is not it funny? S* |

Free electron laser it is a quite different thing than laser. The free electron laser produces the "laser-like" light: " As the electrons are undergoing acceleration they radiate electromagnetic energy in their flight direction, and as they interact with the light already emitted, photons along its line are emitted in phase, resulting in a "laser-like" monocromatic and coherent beam".

Unfortunately, I understand completely. Laser = "laser - an acronym for light amplification by stimulated emission of radiation" Laser rework natural light (radiation). Antennas produce artifical radiation in the result of the electron oscillations. To make the oscillations we use different devices. LC for radio waves, megatrons for microwaves, claystrons for radar waves and the Halbach array for the light frequency. The word "laser" is probably common name for the all atificical light sources.
