A laser pulse (27 fs, 2.7 J, 800 nm) ionizes a gas jet and accelerates the freed electrons by the ponderomotive force and subsequent plasma wakefields.

Caption

The accelerating electrons radiate coherent THz emissions continuously along the laser propagation direction, resulting in broadband multi-mJ THz radiation in the far field.
