Abstract

Terahertz (THz, 10¹² Hz) frequency radiation has long proven to be elusive relative to microwaves at lower frequenc ies and infrared radiation at higher frequencies. We have investigated several solid-state materials as candidate terahertz-frequency emitters under excitation by ultra-short (12 fs) pulses of near-infrared radiation, and present the results here with a comparison between different emission mechanisms.
