Abstract: At absolute zero of temperature,we derive the analytic expression for the time evolution of the light  -field in the single-mode dissipative cavity under both Fock state and coherent field. Also,we present a new derivation in the presentation of the number states,which is different from textbooks.

Key words: photon, dissipative cavity, coherent state, Fock state
