    Abstract

    The energy up-conversion from the kinetic Alfven wave turbulence to the ordinary mode radiation through the plasma-maser process is studied. Thegrowth rate of the ordinary mode originates from two mode-mode coupling terms, viz: The direct and polarization terms. In contrast to the previous electrostatic wave case, both contributions give large growth rate forthe ordinary mode radiation. The results have potential importance tointerpret numerous astrophysical radio phenomena, because the magnetohydrodynamic (MHD) waves contain the dominant turbulent fluctuationsin astrophysical plasmas.
