  • Abstract In this thesis, photoconductive antenna THz generation and EO sampling detection with ZnTe time-domain spectroscopy system is demonstrated. Using this THz TDS system, chirp-controlled THz enhancement is characterized through two photon absorption induced extra-photocarrier and narrow band THz.
    In two photon absorption enhancement, an anomalous THz radiation enhancement is observed and attributed to two-photon absorption induced extra-photocarrier. Besides, increasing high frequency component is also performed as theoretical expectation. This provides a novel potential for broadband THz radiation.
    For narrow band THz radiation enhancement is studied using chirp controlled double pulses generated with Michelson Interferometer. Specific frequency enhancement is observed as corresponding temporal spacing pulses applied for excitation. Meanwhile, more enhancement with positive chirp is studied and discussed as well.
