283.3 nm紫外激光激发铅原子束光谱
Spectra of atomic lead beam by UV 283.3 nm laser excitation
摘要
利用原子束装置测量了在紫外激光283.3 nm激发下铅原子的荧光光谱,研究了在不同激发强度下的荧光光谱特性.考虑到激发态自发辐射和光离化过程的竞争,使用三能级速率方程很好地解释了荧光强度与激发强度的关系.
Abstract
Atomic fluorescences in a Pb beam excited by a UV tunable laser were measured under different exodting intensities. Theoretic analysis is based on the three-level rate equation, which includes a process of two-photon ionisation. A good agreement was obtained between the experiment and the calculation.
