We theoretically study the stacked optical transients generated from a series of square
pulses passing through a cold atomic ensemble. Using the hybrid analysis and fast Fourier
transform, we identify the stacked coherent transients [Europhys. Lett. 4, 47 (1987)] as
optical precursors. With slow-light and electromagnetically induced transparency, we obtain
nearly 700% transmitted intensity at the transient spikes resulting from the interference
between the delayed main field and the stacked optical precursors.
