Raman Optical Lattice

ORAL

Abstract

It is shown that sub-Doppler cooling occurs in an atom-field geometry that can lead to reduced period optical lattices. Four optical fields are combined to produce a standing wave Raman field that drives transitions between two ground state sublevels. Semi-classical solutions of the atomic momentum distribution are calculated and compared with both experimental results and Quantum Monte Carlo Wavefunction simulations.
