| Abstract: | New results on growth and decay times of the stimulated electromagnetic emission (SEE), obtained using a special quasi-continuous schedule of HF pump wave radiation, are presented. The employed technique allows to study the evolution of HF plasma turbulence with a high time resolution ( 0.25 ms). It is established that for the broad continuum SEE component the emission intensity starts to decrease within the delay time τD 0.5−3.2 ms after pump wave turn-off, where longer times correspond to lower SEE frequencies. The effect is explained in terms of transfer of HF-excited plasma waves throughout their spectrum due to induced scattering by thermal ions. |
