Steering Laser-Produced THz Radiation in Air with Flying Focus
We demonstrate that a single-color ultrashort optical pulse generating a short plasma string in air can emit THz radiation along any direction with respect to its propagation axis. The emission angle can be adjusted by the flying focus technique [1], [2], which determines the speed and direction of the ionization front.
