We show theoretically that the propagation of light can be slowed down considerably using the method of coherent hole-burning in a Doppler broadened three-level lambda-type atomic medium without the Doppler-free configurations. The reduction of group velocity of light pulse is achieved by the application of a saturating beam and a strong coupling beam which produce a narrow spectral hole-burning at resonance. We can obtain a larger group index than that using the method of saturation absorption spectroscopy in Doppler-broadened two-level atomic systems.

Coherent hole-burning phenomenon in a Doppler broadened three-level -type atomic system

In a Doppler broadened three-level Λ-type atomic system, we investigate the absorption spectrum of a weak probe laser in the presence of a saturating laser and a coupling laser. We find that, in order to observe coherent hole-burnings effectively, the two lower levels should be so well spaced that atomic collisions can be neglected, and the saturating (coupling) laser should counter-propagate (co-propagate) with the probe laser. We also give a qualitative analysis to understand the physical origin of coherent hole-burnings.
