Abstract
We investigate high-intensity propagation around a free exciton resonance in a semiconductor. Under certain conditions, coherent propagation can be found. We call this new effect `self-induced transmission on a free exciton resonance in a semiconductor'. Tuning the laser towards higher energy, thus exciting continuum states, the degree of transmission is reduced. The pulse breakup vanishes. By increasing the pulse intensity by several orders of magnitude, pulse breakup can be observed again. Using pulses with durations less than 100 fs, pulse breakup can be observed, but the behaviour under increasing pulse intensity is quite irregular. Pulse compression can occur under certain circumstances.
