Abstract

The emission mechanism studied here, the synchrotron maser instability is based on a gyroresonance of highly energetic electrons. Compared to the cyclotron maser, this mechanism has the great advantage to be a direct amplification process even if the ratio ωp/ωc is not very small; a situation relevant to stellar flares.The high efficiency of the process can be confirm by the non linear study of its saturation.
