| Abstract | Strong-field light–matter interactions can encode the spatial properties of the electronic wavefunctions that contribute to the process. In particular, the broadband harmonic spectra, measured for a series of molecular alignments, can be used to create a tomographic reconstruction of molecular orbitals. Here, we present an extension of the tomography approach to systems that cannot be naturally aligned.We demonstrate this ability by probing the two-dimensional properties of atomic wavefunctions. By manipulating an electron–ion recollision process, we are able to resolve the symmetry of the atomic wavefunction with high contrast. |
