Influence of atomic motion on the population and dipole squeezing of a cascade three-level atom in cavity field
Ai‐Dong Zhu, Zhang Shou · Chinese Physics · 2004
The dynamical property of a cascade three-level atom is investigated in the condition of atomic motion. The influence of atomic motion on the population and dipole squeezing is discussed. The results show that atomic motion makes the amplitude of atomic population be steady and increasing the parameter ε p which denotes the atomic motion and the structure of field mode can shorten the period of collapse–revivals. By choosing an appropriate parameter ε p , we can obtain a dipole squeezed atom of long standing.
