  • Abstract
    A terahertz time-domain system with continuous bandwidth extending from millimetre wave through the mid-infrared is demonstrated using ionising air as the generation and detection medium. The measurements indicate that the bandwidth of such systems is constrained only by the optical pulse duration utilised. With use of a 25 fs pulse duration laser, a continuous bandwidth reaching 40 THz is demonstrated.
