Abstract :
Emission of terahertz radiation is observed when a single layer graphene on a glass slide is excited with femtosecond near-infrared laser pulses. Furthermore, we can enhance the amplitude of terahertz emission by surface plasmon resonance excitation on a thin gold film in the Kretschmann geometry.
