Terahertz (THz) waves generated through four-wave mixing in laser-induced air plasmas are an ideal source for imaging arbitrary locations. Under an amplified laser beam, ionized ambient air as a mixing medium provides broadband pulses with an unprecedented THz electric field strength among all the optically induced THz waves from nonlinear materials. We report the use of plasma-induced THz waves for 2D imaging for the first time, and compare it to other methods.
