广义的说,激光化学是研究激光与物质的相互作用。它与传统光化学的差别的一个主要点是以前所用的是汞灯等各种非相干光源所引发的化学反应,而激光化学的独到之处在于利用激光的高强度、短脉冲。它不仅可以研究高激发电子态物质的特性(包括里德堡态原子的化学特性),而且可利用强红外激光作用下实现多原子分子的红外多光子离解。这是过去传统光化学无法实现的。激光化学发展的第一个阶段是激光分离同位素,特别是以激光分离铀同位素为主要课题,大约发展了近十种激光化学的分离方法并探讨
Broadly speaking, laser chemistry is the study of laser-matter interactions. One of the main points of its difference from traditional photochemistry is the chemical reaction that has previously been caused by various incoherent light sources such as mercury lamps. The uniqueness of laser chemistry lies in the use of high-intensity, short-pulse laser light. It can not only study the properties of highly excited electronic states (including the chemical properties of atoms in Rydberg state), but also make use of strong infrared laser to achieve polyatomic infrared multi-photon dissociation. This is past traditional photochemistry can not be achieved. The first stage of laser chemical development is laser separation of isotopes, especially the laser separation of uranium isotopes as the main issue, the development of nearly 10 kinds of laser chemical separation methods and to explore
