SUMMARY:Applications of the 6s-5d quadrupole transition in neutral Ces
 ium atoms\, Preliminary Exam\, Hong Ming Lim \, Physics PhD Graduate S
 tudent
DESCRIPTION:The 6s–5d electronic transition in neutral cesium atoms 
 is a forbidden transition\, and therefore has a narrow linewidth. This
  transition can be used in laser cooling to achieve a low Doppler temp
 erature. One limitation of the conventional imaging method for atomic 
 states through allowed transitions is the background light arising fro
 m the excitation laser scattered by surfaces and objects near the trap
 ped atoms. Excited cesium atoms in the 5d state decay primarily throug
 h dipole-allowed transitions to intermediate states and emit photons a
 t wavelengths longer than that of the excitation laser. This property 
 can be used to perform background-free\, state-selective fluorescence 
 imaging\, enabling higher fidelity and shorter imaging times. In this 
 talk\, I will present an overview of the experiments we are conducting
  to push the limits of high-fidelity\, fast atomic state readout using
  this transition.
