摘　　要：飞秒强激光作用下,分子发生多电荷电离,产生高价分子离子.由于电荷间的库仑排斥作用,高价分子离子会发生库仑爆炸,生成的碎片离子具有较大平动能量.本文结合在北京大学开展的飞秒强场分子库仑爆炸研究,介绍了飞秒强激光驱动的分子库仑爆炸的重要进展、潜在应用和未来发展方向.When molecules are irradiated by intense femtosecond laser pulses, multiple ionization occurs and multiply charged molecular ions are generated. Due to the Coulomb repulsive force, multiply charged molecular ions will quickly dissociate into fragmental ions with high kinetic energy through the process of so-called Coulomb explosion. In this review article, we introduce the important achievements, potential applications and future development of laser-driven Coulomb explosion of molecules based on the study of Coulomb explosion of molecules by intense femtosecond laser pulses at Peking University.
