Laser ablation in liquid (LAL) can create a microenvironment with transient extreme high temperature and pressure and provide an ultrafast quenching rate, which makes it a general method to fabricate metastable nanomaterials or efficiently synthesize compounds. LAL is a technology that uses a pulsed laser to ablate the solid target or liquid in the liquid phase to create a transient local high-temperature and high-pressure microenvironment for the fabrication of nanomaterials or compounds. LAL is generally carried out in the liquid under room temperature and atmospheric pressure. However, it can create a local environment with special thermodynamics and kinetics under extreme conditions in the liquid. Compared with the traditional laser ablation in a vacuum or diluted gas environment, LAL shows a unique thermodynamic and kinetic mechanism, which makes it a unique new technology for the fabrication of nanomaterials and compounds under special extreme conditions. 



Bo Yan received his Ph.D. from Sun Yat-Sen University, China (supervised by Prof. Guowei Yang). He now serves as a postdoctoral fellow in Prof. Guowei Yang's research group. During his doctoral and postdoctoral research, he has published over 30 papers, including 13 first-author papers and six papers with impact factors over 10. During his doctoral studies, he was supported by the Innovation and Development Programs for outstanding postgraduates at Sun Yat-Sen University. During his postdoctoral period, he was supported by the General Fund Programs for postdoctoral researchers and participated in the General Fund Programs of the National Natural Science Foundation of China.
