The possibility of generation of terahertz superradiance (SR) pulses in the case of incidental scattering of a laser pulse by a high-current relativistic electron beam with frequency conversion down is analyzed. Scattered radiation propagates in the opposite direction (with respect to the translational velocity of the particles). It is shown that when using pulses with an energy of 3 kJ at a wavelength of 1 μm as a pump during optimization of the laser pulse duration and the length of the interaction region, it is possible to generate pulses of scattered counter (relative to the translational particle velocity) radiation with a power of the order of 580 kW and a duration of 30 ps at a wavelength of 100 μm.

Beam Collimation

Abstract The double laser pulse approach to relativistic electron beam (REB) collimation in solid targets has been investigated at the LULI-ELFIE facility. In this scheme two collinear laser pulses are focused onto a solid target with a given intensity ratio and time delay to generate REBs. The magnetic field generated by the first laser-driven REB is used to guide the REB generated by a second delayed laser pulse. We show how electron beam collimation can be controlled by properly adjusting the ratio of focus size and the delay time between the two pulses. We found that the maximum of electron beam collimation is clearly dependent on the laser focal spot size ratio and related to the magnetic field dynamics. Cu-Kα and CTR imaging diagnostics were implemented to evaluate the collimation effects on the respectively low energy (≤100 keV) and high energy (≥MeV) components of the REB.
