| Abstract: | A Cherenkov-type terahertz electromagnetic radiation is revealed,
which results efficiently from the collective effects in the
time-domain of ultrafast pulsed electron current produced by
ultrafast intense laser--plasma interaction. The emitted pulse
waveform and spectrum, and the dependence of laser pulse parameters
on the structure of the radiation field are investigated numerically.
The condition of THz radiation generation in this regime and
Cherenkov geometry of the radiation field are studied analytically. |
