The high harmonic generation (HHG) from the CS2 molecule in intense laser fields is investigated using the extended Lewenstein method.The initial state is the highest-occupied molecular orbital of the CS2 molecule,which can be well described by Gaussian wave packet using GAMESS-UK package.Compared with the case of the elliptical laser,the HHG can be extended in two-color circularly polarized laser field.The time-frequency analysis and classical electron trajectory as well as the ionization yield curve are also presented to further explain the underlying mechanism.After adding a static electric field on the z-direction,the single quantum path control is realized and the supercontinuum spectra are obtained.Moreover,an isolated 110 as pulse can be obtained by superposing the harmonics from 130th to 180th order.
