Abstract
We propose a general concept to use the spatial information encoded in the time-dependent polarization of high-order harmonic radiation generated by orthogonally polarized two-color laser fields. Based on polarization selective detection, we present two examples of applications: (i) a method for isolating a single attosecond pulse from an attosecond pulse train which is more efficient than the cutoff selection method and (ii) a technique for orbital tomography of molecules with attosecond resolution.
