An Experimental Investigation of Radiation Trapping in Optical Molasses
In this thesis, the effect of radiation trapping on the photon statistics of the light scattered from optical molasses is experimentally investigated. It is demonstrated that the intensity correlation function is sensitive to the presence of radiation trapping at an on-resonance optical depth, OD, as low as 0.1. It is also shown that it is possible by introducing a mild anisotropy in the trapped cloud to change the number density of a trapped sample of laser-cooled atoms in a dilute magneto-optical trap by over an order of magnitude, from 1.9 x 10 ^9 atoms/cm ^3 to 1.6 x 10 ^8 atoms/cm ^3 , while keeping the temperature constant.
