Generation of elliptical isolated attosecond pulse from oriented H2+in a linearly polarized laser field
文献摘要：
We investigate the ellipticity of the high-order harmonic generation from the oriented H2+exposed to a linearly polar-ized laser field by numerically solving the two-dimensional time-dependent Schr?dinger equation(2D TDSE).Numerical simulations show that the harmonic ellipticity is remarkably sensitive to the alignment angle.The harmonic spectrum is highly elliptically polarized at a specific alignment angle θ=30°,which is insensitive to the variation of the laser parame-ters.The position of the harmonic intensity minima indicates the high ellipticity,which can be attributed to the two-center interference effect.The high ellipticity can be explained by the phase difference of the harmonics.This result facilitates the synthesis of a highly elliptical isolated attosecond pulse with duration down to 65 as,which can be served as a powerful tool to explore the ultrafast dynamics of molecules and study chiral light-matter interaction.
