N-benzyl-2-methyl-4-nitroaniline (BNA) fiber single crystals were grown by the micro-pulling down (µ-PD) method. Crucible material and its shape were selected based on wetting of the crucible material by liquid BNA. As a result, BNA fiber single crystal with about 1–2 mm diameter was successfully grown. Powder XRD analysis and X-ray rocking curve measurements were performed. Widely-tunable THz-wave generation from 4 THz to 14 THz was demonstrated using the BNA fiber crystal grown by µ-PD method.
