A new enhanced radiation process from plasma turbulence (plasma-maser) is interpreted as “dissipative structure” in plasma turbulence. The plasma-maser process is effective in an open plasma system where some of the input energy is dissipated as anomalous radiation. The validity of the linear response theory which neglects the ensemble averaged second order electric field is given under the random phase approximation. The ordinary mode growth rate in the presence of the enhanced stationary Langmuir turbulence is obtained and the results have potential importance to clarify the mechanism of the anomalous radiation in plasma astrophysics.
