Abstract

We describe the use of a coupling electromagnetic field to provide a general method of producing inversion-free laser systems. The interference between dressed states produces a zero in absorption while allowing gains of the order of that of the uncoupled 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.

Lasers without inversion: Interference of lifetime-broadened resonances

Stephen E. Harris

We show that if two upper levels of a four-level laser system are purely lifetime broadened, and decay to an identical continuum, then there will be an interference in the absorption profile of lower-level atoms, and that this interference is absent from the stimulated emission profile of the upper-level atoms. Laser amplification may then be obtained without inversion. Examples include interfering autoionizing levels, and tunneling systems.

Non-Reciprocity of Autoionizing Interferences: Lasers Without Inversion

Stephen E. Harris

Interferences of autoionizing lines may reduce or eliminate absorption of lower level atoms. Stimulated emission shows no such interferences, thereby allowing laser gain without population inversion.

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 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.

Electromagnetically induced absorption and transparency in a ladder-type atomic system with different dressing mechanisms

Hao-Wei Ti, X. Q Yan, H P Liu +6 more

In a Doppler-broadened ladder-type Rubidium atomic system [Formula: see text]–[Formula: see text]–[Formula: see text], three-photon electromagnetically induced absorption (EIA) and transparency (EIT) in two schemes of two coupling lasers with different propagation directions are comprehensively studied. Two coupling fields are entangled tightly with each other and induce constructive interference such that we observe EIA as two coupling fields are counter-propagating. Two coupling fields are independent and cause destructive interference such that only enhanced EIT occurs when two coupling fields are co-propagating, although all of the Doppler-broadened atoms satisfy the condition for three-photon resonance. The experimental results are coincided with the numerically calculated spectra using the dressed perturbation method. The mechanisms of EIT and EIA could also be understood by the dressed-state pictures.
