Coherent oscillations with frequency in the range 20-80kHhas been observed in thermal plasma jet close to the nozzle exit.From a phase shift of the oscillations along the,jet,the wave phase velocity was evalueted.The phase velocity was substantially smaller than the plasma velocity.The dependencies of frequency,amplitude and phase velocity of the oscillations on parameters of plasma jet and on position in the jet were determined.
