Abstract We demonstrate the efficient generation of ultraslow bright and dark optical solitons in a lifetime-broadened three-level atomic medium by using only a low-intensity pulsed laser radiation. The proposed scheme may be useful, in principle, for the control technology of optical delay lines and optical buffers.
