High-Order Harmonic Generation in Laser-Irradiated Homonuclear Diatomics: The Velocity Gauge Version of Molecular Strong-Field Approximation

Vladimir I. Usachenko, Pavel E. Pyak, Shih-I Chu

The generation of high harmonics in laser-irradiated light homonuclear diatomics (H2+, N2 and O2) compared to that in atomic counterparts (of nearly identical binding energy) is st…
