  • Abstract
    The characteristics of photogenerated terahertz (THz) pulses radiation about 450 fs wide from a current-biased superconducting YBa2Cu3O7-δ (YBCO) bow-tie antenna were investigated using a free-space electro-optic sampling technique. The dynamics of the quasiparticles optically induced by the ultrafast laser pulse primarily determines the performances of the transient THz radiation generated under different operating parameters are discussed.
