Abstract |
|
|
| The study analyzed the squeezing and statistical properties of the light generated by a degenerate three-level atom driven by coherent light. It also discussed a closed cavity coupled to a vacuum reservoir via a single-port mirror. The analysis is carried out by putting the noise operators associated with the vacuum reservoir in normal order and by applying the large-time approximation. We have found that the photon number statistics is sub-Poissonian for η < 0.15 and super-Poissonian for η ≥ 0.15. In addition, the quadrature variance and the quadrature squeezing of a cavity mode were determined and the result shows that the cavity mode is in a squeezed state and the squeezing occurs in the minus quadrature. The maximum quadrature squeezing is found to be 43.6%, below the coherent-state level.
