| Abstract: | The conditions for realizing lasing without inversion are investigated via density matrix method in bare and dressed states in the V-type closed lifetime-broadened system where atomic coherence is induced by an external electromagnetic field. It is shown that a proper choice of pumping rate may lead to the realization of lasing without inversion. |
