We present an experimental and theoretical study of high‐intensity femtosecond pulse propagation on the free exciton resonance in CdSe. The results include pulse reshaping, pulse break‐up, high transmission rates and a dip in the velocity dispersion for pulses tuned to the vicinity of the A‐exciton. This corroborates evidence for nonlinear coherent on‐resonance long‐distance propagation in semiconductors.
