Abstract. An experimental study of the molecular gas interaction with phase diffusion field and a coherent signal was presented. The noise radiation source employed in the experiment was an oscillator based on the BiSrCaCuO HTS mesa structure. The coherent signal was produced by a backward-wave oscillator. The experiment shows that the effect of the noise signal on the molecular gas is similar to coherent one.
