      abstract     = {Highly-efficient optical generation of narrowband terahertz
                      radiation enables unexplored technologies and sciences from
                      compact electron acceleration to charge manipulation in
                      solids. State-of-the-art conversion efficiencies are
                      currently achieved using difference-frequency generation
                      driven by temporal beating of chirped pulses but remain,
                      however, far lower than desired or predicted. Here we show
                      that high-order spectral phase fundamentally limits the
                      efficiency of narrowband difference-frequency generation
                      using chirped-pulse beating and resolve this limitation by
                      introducing a novel technique based on tuning the relative
                      spectral phase of the pulses. For optical terahertz
                      generation, we demonstrate a 13-fold enhancement in
                      conversion efficiency for $1\%-bandwidth,$ 0.361 THz
                      pulses, yielding a record energy of 0.6 mJ and exceeding
                      previous optically-generated energies by over an order of
                      magnitude. Our results prove the feasibility of
                      millijoule-scale applications like terahertz-based electron
                      accelerators and light sources and solve the long-standing
                      problem of temporal irregularities in the pulse trains
                      generated by interfering chirped pulses.},
