Special line-shapes of two-photon transitions in a Y-type four-level system based on quantum interference

Abstract

The experimentally observed special lineshape, induced by the interaction between two counter-propagating equal-frequency fields and a Y-type four-level system with two mixed upper levels, has been analysed theoretically. Serious lineshape variations of the two-photon transitions due to quantum interference are discussed and predicted.

Quantum Interference Effects in Molecular Y- and Rhomb-Type Systems

H.-R. Xia, Cen-Yun Ye, Jian-We Xu +1 more

In this paper we report the first observation of molecular population trapping in four level systems. Constructive and destructive quantum interferences between two sum-frequncy two-photon transitions in Y- and rhomb-type four-level systems, respectively, im sodium molecules have been experimentally achieved by using only one laser source. Their energy level schemes are featured by the extremely near-resonant enhancement of the equal-frequency two-photon transitions, sharing both the initial and the intermediate levels for the Y-type, and sharing both the initial and the final levels for the rhomb-type systems. Their novel spectral effects are to show seriously restrained Doppler-free UV peak at the nominal location of the induced two-photon transition with visible fluorescence in rhomb-type schems, and to show a strong extra UV peak but null visible fluorescence in the middle between the two dipole allowed two-photon transitions.

Spontaneous emission from a double V-type four-level atom in a double-band photonic crystal

Han Zhuang Zhang, Jian Bing Yang, Sing Hai Tang

Quantum interferences in spontaneous emission from a double V-type four-level atom in a double-band photonic crystal have been investigated. The double V-type transitions from the two upper levels to the two lower levels can interact not only with modes near the edges of a double-band photonic band gap, but also with free vacuum modes. The resulting two types of quantum interferences give rise to not only dark lines, but also a narrow spontaneous line in the spectrum from the transition coupled to the free vacuum modes. The dark lines and narrow spontaneous line are shown to be dependent on the width of the forbidden gap, relative position of the upper levels from the band edges, coupling constants, and initial coherent superposition state of the system.

Line shape, frequency shift, Rabi splitting, and two-photon resonances in four-level double-resonance spectroscopy with closely spaced intermediate levels

Swapan Kumar Mandal, Pradip Narayan Ghosh

The interaction of a four-level atomic system with two electromagnetic radiations has been studied. The two intermediate levels are closely spaced such that a single radiation frequency can induce transitions from the ground state to both of them. In a cascade-type double resonance, the pump electric-field amplitude is much stronger than the amplitude of the signal field, which can induce transitions from both of the intermediate levels to the upper state. The 15 optical Bloch equations obtained from the Liouville equations are solved analytically to obtain the Doppler-free signal line shape. The computed signals, exhibiting two Lorentzian line profiles, are presented for different pump frequencies. In addition to these one-photon transitions, we obtain a weak two-photon resonance peak. The two-photon resonance becomes weaker when the detuning of the pump frequency from a resonance frequency is increased. When the pump frequency ${\mathrm{\ensuremath{\Omega}}}_{\mathit{p}}$ is intermediate between the pump resonance frequencies ${\mathrm{\ensuremath{\omega}}}_{1}$ and ${\mathrm{\ensuremath{\omega}}}_{2}$, the two-photon resonance is very weak and almost vanishes when ${\mathrm{\ensuremath{\Omega}}}_{\mathit{p}}$=(${\mathrm{\ensuremath{\omega}}}_{1}$+${\mathrm{\ensuremath{\omega}}}_{2}$)/2. When the pump frequency is on resonance with one of the transition frequencies, the Rabi splitting of the signal shows asymmetry because of the presence of a close-lying transition which is pumped off resonance. The intensity-dependent shifts of the transitions are such that they repel each other more and more as the intensity of the pump field is increased. These shifts arise from the nonresonant interaction between the atom and the field.

Interference of a Narrowband Biphoton with Double Electromagnetically Induced Transparency in an N-Type System

Peng Chen, Jun Qian, Dong-Yuan Chen +2 more

We predict the possibility of the interference of narrow-band biphotons generated by spontaneous four-wave mixing with double electromagnetically induced transparency configuration in cold atoms. In an N-type four-level system, an auxiliary optical field Ω m can create double transparency windows for anti-Stokes photons. When the slow light effects in the double transparency windows are very strong, two four-wave mixing channels could exist due to the splitting of the phase matching condition. The biphoton generated from the two four-wave mixing channels can cause interference and shows Rabi oscillations in two-photon correlation. This interference mechanism will complement the understanding of interference at the two-photon level.

Two-photon excitation via quantum interference

Neil Mulchan, Min Yan, D. G. Ducreay +1 more

Summary form only given. It has been shown that two-photon absorption can be controlled by quantum interference in the multiple excitation paths created by a coupling field. Recently, Harris and Yamamoto (1998) described a four-level system that utilizes electromagnetically induced transparency (EIT) to switch on and off the two-photon excitation. Because the cancellation of the one-photon excitation, the enhanced two-photon excitation may be observable under very low light intensities. We have carried out an experimental study of two-photon excitation via quantum interference in multi-level Rb atomic systems based on the D/sub 1/ and D/sub 2/ transitions. The Rb systems can be viewed as quasi-four level systems. The experiments were done in an /sup 87/Rb isotope vapor cell.
