An all optical dynamical dark trap for neutral atoms

P. Rudy, R. Ejnisman, A. Rahman, S. Lee, and N. P. Bigelow

Open Access Open Access

Abstract

We describe the experimental realization of a dynamical optical trap for atoms: the Rotating Off-resonant Dipole Optical (RODiO) Trap. A blue detuned circularly scanned laser beam creates a time averaged “box” for the atoms. We characterized this novel confinement technique by varying the trapping geometry and the laser beam parameters. Our observations agree well with a numerical model.

The inset shows the 1/e expansion and escape time of the atom cloud released from RODiO as probed by induced fluorescence. The decay time reflects the velocity distribution of the atoms confined by the RODiO just before their release.
