- •
We investigate the HHG and the spatial distribution in HHG of the H2+ molecule by a time-delayed two-color laser field.
- •
The time-delay will change the electron recombined with the nuclei along the positive- or negative-z direction.
- •
We perform the classical analysis which is consistent with the numerical results from the non-Born-Oppenheimer TDSE.
- •
When the time delay is 1.34 fs, an isolated attosecond pulse with a duration of about 99 as is generated.
