首次发现了在不同保护气体及多脉冲UV-IR激光的照射下，液态金属的微型突起和微结构的形成。测量表明，针对不同的金属和保护气，这种结构的单脉冲生成速率可达(5~20) μm/pulse，形成了长度为1~2 mm，直径约为焦点两倍的单个微型突起。最后，介绍了控制微结构形状的可能性，并讨论了它们的应用潜力。

Formations of stable micro-protrusions and microstructures on the surfaces of liquid metals during multipulse action of a UV-IR laser in different ambient gases was discovered for the first time. The rate of the structure formation was measured, which can reach 5-20 μm/pulse depending on the metal and ambient gas sort. Single micro-protrusions of 1-2 mm in length were formed with the diameter approximately two times greater than the focal spot size. The possibility to control the microstructure shape was shown and their potential applications were also discussed.
