We demonstrate the first experimental observation of ultrafast electron-spin polarization upon photoionization using femtosecond and nanosecond lasers. For the optical detection of electron-spin polarization we measure the laser-induced fluorescence of photoions. The experimental results agree well with our theoretical results obtained by solving the time-dependent Schroedinger equations.
