| Abstract: | The problem of the decoherence of two-level atom being put in a thermal reservoir through an external controllable driving field is studied in high -intensity cavity.The non-opposite angle element of two-level atom's reducible density rectangular array is obtained in three photon processes.We discuss the properties of an external driving field when atom's decoherence vanish from sight. |

| Keywords: | two- level atom three photon processes decoherence an extemal controllable driving field |
