| Abstract: | The entropy evolution of the field in interaction of two coupling two-level-atoms with coherent state is studied.Using Tavis-Cummings model,the influences of coupling constants between atoms and intial mean photon number of field on entropy evolution of the field is studied.The results obtained using the numerical method show that with decreasing of coupling constant between atoms and increasing of intial mean photon number of field,The entropy evolution of the field is getting stronger. |

| Keywords: | two coupling two-level-atoms coherent state the evolution of the field entropy |
