      abstract     = {In this work, we have studied the limitations of narrowband
                      multi-cycle (MC)terahertz (THz) generation via optical
                      rectification (OR) in periodically-poled lithium
                      niobate(PPLN) crystals. Detailed investigation of the
                      transmitted beam profile, THz conversionefficiency (CE), and
                      parasitic second-harmonic generation (SHG) strength as a
                      function ofincident pump beam size showed that Kerr-lensing
                      is a significant bottleneck in the efficiencyscaling of MC
                      THz generation. We have also demonstrated that compared to
                      the usage of asingle pump pulse, excitation of the PPLN
                      crystal via a pulse train, not only boosts up THzCE and
                      narrows down the bandwidth of the achieved THz beam but also
                      helps to mitigate theeffect of undesired nonlinearities,
                      such as Kerr-lensing, and parasitic SHG.},
