Atomic Physics Seminars

Physics Building, Room 204
Note special time.
Vincent Carrat , University of Virginia
[Host: Tom Gallagher]
As a demonstration, we used our SLM to produce Laguerre-Gaussian beams in order to guide over a long distance a cold rubidium beam supplied by a 2D-MOT. We have strongly reduced the divergence of this source and thus increasing by a factor of 200 the atomic density after a propagation of 30 cm. Furthermore we showed that in such a guide the spontaneous emission is lower than in the usual red detuned gaussian guide case.
