N2 - We demonstrate the generation of single-cycle longitudinally polarized terahertz pulses with fieldamplitudes in excess of 11 kV/cm using the interferometric recombination of two linearly polarizedterahertz beams. High field strength transversely polarized pulses were generated by optical rectificationin a matched pair of magnesium-oxide doped stoichiometric lithium niobate (MgO:SLN)crystals with a reversal in the vð2Þ333 orientation. The discontinuity in vð2Þ333 produces a polarity flip inthe transverse field; the longitudinal field produced as a consequence of the transverse field discontinuitywas measured in the far-field. Both the spatial and temporal profiles of the measured longitudinallypolarized terahertz radiation were consistent with the propagation of the transversediscontinuity.
