Coherent population trapping in a closed transition

Abstract

This paper provides insight into the behaviour of the coupling laser which occur in a typical electromagnetically induced absorption closed transition. In this research different closed transitions of the /sup 133/Cs D/sub 2/ line are analysed with a probe and a coupling laser. A phenomenological computational model of the dispersion pattern is also developed, which gives good agreement with the taken measurements. A full theoretical analysis of the details for the system is presently under development.
