A table-top THz source has been employed to study the nonlinear response of semiconductors to near-half-cycle intense femtosecond pulses. We report nonlinear field-induced changes in the far infrared absorption coefficient, associated with THz-induced impact ionization processes occurring within the THz pulse.
