Numerical simulation of strong-field electron spectra of Xe in the rescattering region
- College of Physics, Liaoning University, Shenyang 110036 (China)
We investigate the high-energy above-threshold ionization (HATI) plateau for Xe in a strong laser field at peak intensity of about 0.85x10{sup 14} W/cm{sup 2} with wavelengths of 800, 1250, 1500, and 2000 nm. Numerical simulations are performed using a recently developed quantitative rescattering (QRS) model. According to the QRS model, the two-dimensional (2D) photoelectron momentum distribution can be treated as a product of the returning electron wave packet and the elastic differential cross section (DCS) for free electrons scattered with the parent ion. From the 2D momentum distributions, the HATI plateau can be obtained. By using different single-active electron potentials in the DCS calculations, we test the potential dependence of the high-energy plateau spectra. Good agreement between the simulated results and the experimental data confirms again the validity of the QRS model.
