Abstract

We report on our experiments on nonlinear magneto-optical effects in laser-cooled, near-degenerate rubidium samples. Atoms are laser-cooled and subsequently transferred to the crossed-beam optical dipole trap (ODT), formed by a tight focusing of 1560-nm laser beams. The trap not only provides long relaxation time but also allows us to investigate the quantum degeneracy regime. Moreover, the tight confinement of atoms enables magnetic field probing with a high spatial resolution of a few tens of micrometers.
