Spatio-spectral technique to verify pump-pulse propagation model in an Ar-filled capillary in the presence of high harmonic generation
High-power ultrashort laser pulses propagating in gas-filled capillaries can form a compact source of extreme ultraviolet (XUV) and soft X-ray radiation by high-harmonic generation (HHG) [1]. Maximisation of the frequency conversion requires a detailed understanding of the atom-light interaction mechanism as well as the propagation properties of both the near-infrared pump in the presence of a partially ionized gas, and of the generated XUV. Previous theoretical studies of capillary based HHG by Christov et al. [2] have used numerical solutions of the 3-dimensional version of the scalar wave equation.

Abstract
High-power ultrashort laser pulses propagating in gas-filled capillaries can form a compact source of extreme ultraviolet (XUV) and soft X-ray radiation by high-harmonic generation (HHG) [1]. Maximisation of the frequency conversion requires a detailed understanding of the atom-light interaction mechanism as well as the propagation properties of both the near-infrared pump in the presence of a partially ionized gas, and of the generated XUV. Previous theoretical studies of capillary based HHG by Christov et al. [2] have used numerical solutions of the 3-dimensional version of the scalar wave equation.
