Squeezing Properties of Atomic Laser in Two-Mode Squeezed Field Interaction with Bose-Einstein Condensate of Two-Level Atoms
The squeezing properties of atomic laser are studied in two-mode squeezed field interaction with Bose-Einstein condensate (BEC) of two-level atoms within rotating-wave approximation by solving the Heisenberg equation and based on the entire quantum theory. The influence of the interaction among atoms in BEC and the coupling constant between light field and atoms on the depth and duration of squeezing is investigated. The results show that two quadrature components of atomic laser can be squeezed periodically. The duration of squeezing atomic laser depends closely on both the interaction among atoms in BEC and the coupling constant between light field and atoms. The depth of squeezing atomic laser is determined by both the interaction among atoms and the initial squeezing factor of light.
