Abstract
We investigate an active Raman gain scheme for significant group velocity reduction. This scheme, which is fundamentally different from the electromagnetically induced transparency scheme, is capable of achieving ultraslow and distortion-free propagation of a pulsed probe field. The group velocity behavior is drastically different from the conventional electromagnetically induced transparency scheme, and the new scheme can be used to accurately determine the decoherence rate of a long-lived state. In addition, the Raman gain scheme has the advantage of being broadly tunable, an important feature that may have potential applications.
