Abstract

The propagation dynamics of a two-mode ultraslow wave in a three level λ system. The probe modes evolved into a two-mode temporally, amplitude and group velocity (TAG) matched pulse pair after a characteristic propagation which travels without distortion and attenuation in a highly dispersive medium with an atomic density as high as 10¹⁴ cm^-3. Linear and quadratic approximations with numerical calculations were compared for several example using experimental achievable parameters. The results show that four-wave mixing (FWM) process can achieve near unity photon flux conversion efficiency from one mode to the other without the requirement of having maximum atomic coherence.

N1 - We investigate the propagation dynamics of a two-mode probe field traveling with ultraslow group velocities. We show that a strong cross-beam coupling occurs between the two modes of the probe wave in the presence of a two-mode control laser field that maintains two-photon resonance excitations in a three-level system.
