We report the dynamic Franz-Keldysh effect in bulk GaAs. Ultrafast changes in transmission spectra near the band edge, including the first observation of photoinduced transparency as large as 40%, are observed. 2000 Optical Society of America OCIS codes: (320.7130) Ultrafast processes in condensed matter, including semiconductors
