Non-linear terahertz spectroscopy of accepters in p-Ge

We report on the field ionization process of accepters in p-Ge under intense terahertz (THz) electric field. Broadening of the accepter absorption lines followed by disappearance is observed below 10 kV/cm. In the strong field limit, one can see clearly Drude dispersion. This implies that the THz field ionization takes place quite faster than 1 ps.
