(a) Comparison between HHGs obtained from our program and the program SCID-TDSE,^[18] (b) HHG of Ar atom driven by intense laser field (800 nm and 1.0×10¹⁴ W/cm²). U_p represents ponderomotive potential, and I_p denotes ionization energy of hydrogen atom. Cut-off position of HHG is marked with blue dashed line I_p+3.17U_p.
