在饱和激光诱导荧光中，激光束的空间翼是一个非常重要的问题。它们对荧光的贡献通常通过相互作用体积中的激光峰的分辨率来避免。一种替代和通用的方法，制定的基础上，相对于激光强度的衍生物的荧光。事实证明，无翅膀的数据是可能的，尽管它们是从翅膀依赖的荧光中获得的。这种方法的优点是准确的中心线检测和简单的实验装置和程序。
Spatial wings of laser beams are of great concern in saturated laser-induced fluorescence. Their contribution to fluorescence is customarily avoided by resolution of laser peaks in the interaction volume. An alternative and versatile approach is formulated, based on the derivative of fluorescence with respect to laser intensity. It turns out that wing-free data are possible, although they are obtained from wing-dependent fluorescence. The advantages of this approach are exact centerline detection and simplicity of the experimental setup and procedure.
