| Outline of Final Research Achievements |
We demonstrated a novel time-resolved measurement technique using a laser-accelerated femtosecond electron beam for measuring transient electric and magnetic fields produced by intense ultrafast laser interactions with plasmas. A femtosecond electron beam was passed through near a metal wire, and its deflection angle was measured. As a result, we discovered that a high-intensity picosecond electromagnetic surface wave which propagate on the wire with a velocity very close to the speed of light can be produced. This results indicates that an energy of a laser pulse can be converted to an electromagnetic surface wave with the frequency range of sub-terahertz. This phenomenon can be applied to generate high-intensity terahertz waves.
