Abstract
We compare experimental and theoretical studies of the quasi-phase matching (QPM) of high-order harmonic generation (HHG) during propagation of two-color pulses through the indium multi-jet plasmas. Role of the sizes of plasma jets and distance between them on the HHG efficiency at QPM conditions is analyzed. The results of the QPM conditions’ studies provide the reliable interpretation of this phenomenon.
