We demonstrate all-optical control of ultrafast spin polarization upon breakup of a multi-valence-electron system using two-color pump-probe photoionization. For the direct detection of spin polarization, we measure the laser-induced fluorescence of photoions. The experimental results agree well with our ab initio theory.
