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.

Lasing without inversion and coherence in dressed states

Zhenfei Luo, Zhizhan Xu

The V and \ensuremath{\Xi} types of closed lifetime-broadened systems with lower-level-dressed-state preparation by a strong electromagnetic field are analyzed. It is found that the coherence in dressed states enhances the gain in the former system but reduces gain in the latter. However, we show that, since the dressed states are prepared in lower levels, both systems can lase without population inversion in steady state.

Role of atomic coherence in lasing without inversion

Zhenfei Luo, Zhizhan Xu

A noninversion laser system which is closed lifetime broadened and free of the restriction on atomic decay rates is proposed. For the realization of lasing without inversion, the Rabi frequency of the applied field must exceed a lower threshold. Moreover, the coherence term in dressed states must enhance the gain. These results are obtained beyond the specific approximations.

LASING WITHOUT INVERSION: GAIN AND SATURATION

Zhenfei Luo, Zhizhan Xu, LIN FU-CHENG +1 more

The solution for the equations of atomic density matrix is obtained, without resorting to any approximation, in the Ξ-type of three-level system with lower-level coherence. The conditions on pumping are analyzed in the strong-coherence case for lasing without inversion and the saturation term is derived.

Lasing without inversion in a closed three-level system

Yifu Zhu

It is shown that a closed V-type, three-level system, which is incoherently pumped on the transition at which lasing occurs and coherently pumped on the other transition, exhibits lasing without population inversion in any atomic state basis. The same system can be also made to exhibit lasing without population inversion in the bare atomic state basis but with population inversion in the dressed-state basis.

Lasing with and without inversion due to spontaneously generated coherence in an open V-type system

李景娟, 刘呈普, 崔妮 +2 more

It is shown that in an open V-type atomic system without incoherent pumping, the spontaneously generated coherence (SGC) can not only lead to lasing with inversion but also lead to lasing without inversion (LWI) including at resonance of the driving and probe fields. This conclusion is much different from that obtained in the corresponding closed V-type system.

Lasers without inversion: A closed lifetime broadened system

A. Imamolu, J. E. Field, Stephen E. Harris

We show a model laser system which operates by an electromagnetically induced interference. Provided that an inversion condition for the thermal radiation field is satisfied, the system lases without atomic population inversion in steady state. The system is pumped by incoherent radiation on the transition on which lasing occurs.
