Physical Review A
Using a TDDFT method, we calculated the high-harmonic generation (HHG) spectra of N 2 in 800 nm and 1300 nm intense lasers. The calculations reproduce the experimentally observed minimum near 40 eV and the shift of the minimum due to interference of different molecular orbitals. They also support the proposed shape resonance near 30 eV. The TDDFT method allows us to analyze the involvement of different electronic configurations in the HHG process. We identified a significant role of Rydbergdoi:10.1103/physreva.93.013422 fatcat:zwdoybockrhtnooa72naowpicy
