Abstract
The process of a Λ-type three-level atom interacting with the field in an ideal cavity was investigated.By solving the eigen equation,the cavity field spectrum expression of the system was given out.Some numerical results were presented.When the initial field is in a vacuum state,two-peak structure appears for the two degenerate lower levels,and six- or four-peak structure appears for the two non-degenerate ones.The probability amplitudes and relative phase play a decisive role in the spectrum structure when the atom is in a coherent superposition of the two lower levels initially.
