Nondegenerate four-wave mixing in a Doppler-broadened resonant medium
Third-order susceptibilities are calculated for a Doppler-broadened two-level system. The dependence of fourwave mixing on the angle 0 between the pump and signal fields is studied, and the reflection coefficient is shown to have a narrow field of view that is inversely proportional to the ratio of the Doppler width to the homogeneous linewidth. For the collinear geometry, 0 = 0°, the frequency...
متن کاملCoherent interaction of laser pulses in a resonant optically dense extended medium under the regime of strong field-matter coupling
The nonstationary pump-probe interaction between short laser pulses propagating in a resonant optically dense coherent medium is considered. Special attention is paid to the case where the density of two-level particles is high enough that a considerable part of the energy of relatively weak external laser fields can be coherently absorbed and reemitted by the medium. Thus, the field of the med...

متن کاملLaser-pulse compression by coherent control in a Doppler-broadened medium: Analytical and numerical studies
We have studied the temporal compression of laser pulses occurring in a scheme based on the coherent control peculiarities of electromagnetically induced transparency. This work extends earlier model studies, including the effect of Doppler broadening in a real hot medium. For definiteness and consistency of the atomic parameters employed, we have treated a scheme in argon. In this way, we esta...
متن کاملObservation of intracavity electromagnetically induced transparency and polariton resonances in a Doppler-broadened medium.
The transmission spectrum of three-level atoms in a vapor cell inside an optical cavity shows distinct peaks associated with atom-cavity polaritons in the system. We develop the theory of these resonances in a Doppler-broadened medium and present the results of experimental observations of these spectra in three-level Lambda-type rubidium atoms inside an optical ring cavity.
