We perform high-intensity pulse propagation experiments in semiconductors. On a free-exciton resonance, we demonstrate coherent Self-Induced Transmission. Tuning the laser towards higher energy, thus exciting continuum states, the degree of transmission is reduced. The pulse breakup disappears. Increasing the pulse intensity by several orders of magnitude, pulse breakup can be observed again.
