This work provides a theoretical basis for a partially saturated regime of laser-induced fluorescence (LIF), where the dependence of the fluorescence signal on the laser-power is non-linear. Approximate formulas were found that describe the dependence of fluorescence signal on laser pulse energy in commonly used experimental arrangements. The approach developed was applied to the atomic lead measurement and to the study of the decomposition of lead hydride in various versions of flames, diffusion flame and flame-in-gas-shield flame, commonly used hydride atomizers in atomic fluorescence spectrometry.
