Abstract
A Doppler-shifted self-reflected wave is demonstrated through single beam reflection experiments and degenerated pump-probe reflection measurements. Using 150-fs pulses from the second harmonic of a modelocked Ti:sapphire laser, ZnSe is excited to resonant ground state exciton transition at 77 K. At low intensities the pronounced ground state exciton feature can be observed. The excitonic resonance disappears with increasing irradiance. However, the reflected pulse spectrum never resembles that of the incident pulse as it is expected for only stationary changes of the dielectric constant.
