We study experimentally steady-state photorefractive screening solitons trapped in both transverse dimensions and measure their beam profiles as they propagate throughout the crystal. The solitons are observed to be axially symmetric, and they self-bend. We characterize the soliton dependence on the optical intensity, applied electric-field strength, and beam diameter.
