(a) Photo of HTP laser ablation system. (b) Illustration of BNNT synthesis in HTP laser ablation. Boron species evaporate on the surface of the molten boron ball under the continuous radiation of the CO2 laser and react with surrounding nitrogen molecules to form BNNTs (Inset shows the high-speed camera image of the molten boron ball).
