我们今天所掌握的有关原子和分子结构方面的知识,绝大部分来自光谱研究。近年来,由于各种类型激光器的相继问世,使激光光谱学取得了飞速发展。激光与普通光源相比,有许多优点,正是这些优点,使激光能很好地应用于光谱学,让我们对物质的结构、能谱、瞬态变化和微观动力学等有更深入的研究,获得用经典方法无法取得的极为丰富的信息。
The vast majority of our knowledge of the structure of atoms and molecules we have today comes from spectroscopic research. In recent years, due to the success of various types of lasers, laser spectroscopy has made rapid development. Laser has many advantages over normal light sources. These are the advantages that make laser light well suited to spectroscopy, allowing us to study more deeply the structure, energy spectra, transient changes, and micro-dynamics of matter , Access to extremely rich information that can not be obtained with classical methods.
