ABSTRACT
We report on a photocathode for far-infrared terahertz (THz) pulses based on ionization of gas-phase Rydberg atoms. We demonstrate the cathode by showing measurements of the beam profile of an unfocused THz beam in the far field of the emitter using an open ion optics and a contact print image of a spatial mask using THz pulse energies of less than 10 nJ.
