摘要：

High harmonics generation driven by 40 fs laser pulses is investigated in three different noble gases, both in gas and cluster regime depending on gas type and backing pressure. Pressure dependence of the harmonic intensity shows different scaling laws in case of cluster formation compared with monomer gas. Both the higher harmonic yield and the stronger spectral broadening of harmonics in xenon gas show the presence of clusters in the jet. The central wavelength of harmonics has a blue shift increasing with increasing laser intensity which is a consequence of free electron contribution to the phase matching.
