Numerical Simulation of Ion-Based Water-Window Harmonic Generation in Laser-Irradiated Gases

High harmonic generation is driven by short-wavelength electromagnetic waves in laser-plasma interactions. Its conversion efficiency is determined by the relative phase between the driving laser field and the harmonic field, which is affected by various dispersive effects. Therefore, we mainly proposed to achieve the dispersion balance between intrinsic dipole phase variation, Geometrical phase shift, and plasma dispersion under strong ionization regime. The scheme will be verified by numerical simulation for the HHG order 169th by 405-nm laser corresponding to the water window X-ray, i.e. 2.39-nm.
