Molecular-orbital tomography based on high-order harmonic generation has been questioned because of the use of plane-wave approximation.Recently, we have theoretically proposed an approach to tomographically image the valence molecular orbital utilizing a molecular continuum-wave function beyond the plane-wave approximation.We demonstrate the feasibility of this approach using the experimental data and show that the highest occupied molecular orbital of N2 can be successfully retrieved using both Coulomb waves of a Hydrogen-like atom and two-center Coulomb waves.Moreover, we have proposed a scheme for the tomographic imaging of asymmetric molecular orbitals with two-color laser field,which releases the stringent requirement of CEP stable extremely short pulses.
