The interferometric laser cooling and composite pulse schemes explored in this thesis are based on coherent transitions in a two-level atomic system, and we realise this experimentally by inducing stimulated Raman transitions between the ground hyperfine states of rubidium-85. Broadly speaking, a stimulated Raman transition is a two-photon process, whereby two counter-propagating laser beams, far-detuned from resonance with a radiative upper level and with a frequency difference equal typically to the ground hyperfine interval, induce coherent population transfer between (meta)stable states. |
