摘要：

In this paper, the use of squeezed light in laser cooling is investigated. We find that in a traveling-wave laser field, a two-level atom in a squeezed vacuum cannot be cooled to a lower temperature than in normal vacuum. For a two-level atom in a standing-wave laser field, if it is tuned from the resonant region, the conclusion is the same as in the traveling-wave case. However, near the resonant region, the atom in a standing-wave field can achieve a lower temperature than Doppler limit.
