In the paper the theoretical description of experiments [1—3] on the high harmonic generation in cluster
medium irradiated by the laser field of the moderate intensity (1012—1014 W/cm2) is
presented. In these experiments the appreciable expansion of the high harmonic plateau comparing to the case of
irradiating the gas medium is clearly seen. The observation of such effects is possible only if they are coherent.
Special attention is focused to this question.
