AB  - We used pulse trains with 800-fs long pulses and adjustable time delay to investigate the temperature dependence of THz generation in a periodically pooled lithium niobate (PPLN) crystal with a poling period of 400 µm. By adjusting the PPLN temperature (78-350 K), multicycle, narrowband (sub-10 GHz) THz pulses with tunable central frequency in the 253-287 GHz range were obtained. Internal conversion efficiency values up to 0.45
