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 ofH2 and Ne compared to pure gasesH2 or Ne. Our experiments show that at an intensity of ∼1.5 × 1014 W∕cm2 and in mixtures of gases with significantly different ionization potentials (IPs), the initial HHG takes place in the component with lower IP (H2… CONTINUE READING
