| Abstract: | The field entropy evolution and it's squeezing properties of the spontaneous emission in the Jaynes-Cummings system with the atom driven by and detuned from the external classical field are studied,we get the Evolution curve of the field entropy and it's squeezing properties.It shows that the field entropy is influenced by the external field and the dipole coupling constant and the frequency detuning. |

| Keywords: | the driven Jaynes - Cummings model frequency detuning spontaneous emission field entropy entropy squeezing |
