The high harmonic spectra of helium atoms which are exposed to external monochromatic linearly polarized laser fields are calculated by solving the time-dependent non-Hermitian Schrodinger equation. The entire electronic correlation effects with and without the presence of the field are included in our calculations. The full high-harmonic generation spectra HGS were calculated and not only the intensities of the integer harmonics frequencies as calculated before by non-Hermitian quantum… CONTINUE READING
