Abstract Details

2003, Master of Science, Miami University, Physics.
Using three orthogonal pairs of counterpropagating red-detuned lasers and a magnetic field gradient, we have constructed a trap of 85Rb atoms at temperatures reduced to the order of 100 microKelvins and densities of 109 atoms/cm3. When the atoms interact with the light, they are absorbing and spontaneously emitting photons. The emitted photons from atoms can be absorbed by neighboring atoms. This phenomenon, called radiation trapping, limits the density and temperature of the trap and also destroys the atomic coherence. We can non-invasively measure the effects of radiation trapping by measuring the intensity correlation function of the light radiated from the trap. We have found that theoretically, the effects of radiation trapping can be detected in dilute atomic samples with an on-resonance optical depth as low as 0.1, more than an order of magnitude less than seen before. Experimental progress is reported.
