High harmonic generation in Ne and H2 gas mixtures

Abstract

High harmonic generation (HHG) enables the production of coherent light in the extreme-ultraviolet (XUV) spectral region. However, the radiation conversion efficiency from infrared to the XUV is low. We observed enhancement of HHG in gas mixtures of H2 and Ne compared to pure gases H2 or Ne. Our experiments show that at an intensity of 1.5×1014W/cm2 and in mixtures of gases with significantly different ionization potentials (IPs), the initial HHG takes place in the component with lower IP (H2), inducing excited states and facilitating ionization and HHG in the component with higher IP (Ne). We show that the combination of the two gas components results in an enhancement or suppression of the output of high harmonics as compared to pure gases, which is also confirmed by the employed phenomenological model.
