Toward lasing without inversion in the ultraviolet regime: Doppler-free three-photon coherence effects in mercury vapor
نویسندگان
چکیده
Doppler-free three-photon coherence effects at a wavelength of 253.7 nm have been observed in thermal mercury vapor. The experimental results are compared to simulations based on detailed theoretical model reproducing the measured effects. Based these results, we show by that amplification without inversion our setup is feasible, paving way towards lasing mercury.

Lasing without inversion in circuit quantum electrodynamics.
We study the photon generation in a transmission line oscillator coupled to a driven qubit in the presence of a dissipative electromagnetic environment. It has been demonstrated previously that a population inversion in the qubit can lead to a lasing state of the oscillator. Here we show that the circuit can also exhibit the effect of "lasing without inversion." It arises since the coupling to ...
متن کاملEvidence of lasing without inversion in a hot rubidium vapor under electromagnetically-induced-transparency conditions
We report a likely observation of cw lasing without inversion in a gas of hot rubidium atoms in an optical cavity under conditions of electromagnetically induced transparency EIT . The medium is pumped coherently and resonantly by a single “coupling” beam which also produces EIT in the lasing transition. The steady-state intensity exhibits thresholds as a function of the atomic density and the ...
متن کاملLasing without inversion in three-level systems: Self-pulsing in the cascade schemes
Lasing without inversion ~LWI! in specific models of closed three-level systems is analyzed in terms of nonlinear dynamics. From a linear stability analysis of the trivial nonlasing solution of the homogeneously broadened systems with on-resonance driving and laser fields, we find that, near lasing threshold, resonant closed L and V schemes yield continuous-wave LWI while resonant cascade schem...
متن کاملManifestation of Quantum Interference in Lasing Without Inversion *
In terms of quantum interference we demonstrate the physical mechanisms which lead to light amplification without population inversion. The similarities and differences between the two model schemes, namely, A and V-type, are emphasized. A coherent radiation field, on one hand, which drives one of the lasing levels, yields the quantum mechanical two paths via Autler-Townes splittings. On the ot...
متن کاملBlue five-level lasing-without-inversion system in rubidium
We demonstrate continuous coherent blue laser light production using a five-level lasing-without-inversion scheme in rubidium vapor. Two low-power lasers at 780 nm and 776 nm induce a strong atomic coherence in the 5S-5P-5D states. The atoms decay to the 6P excited state from which stimulated emission produces a coherent blue (420 nm) beam. We have coupled both ground-state hyperfine levels, ef...
