Laser Induced Fluorescence [PDF]

open access: yesLaser Chemistry, 1990
Laser induced fluorescence (LIF) has become a common detector of atoms and molecules allowing to determine their internal state distributions. In this paper we mention the advantages of both kinds of lasers, cw or pulsed. We review some aspects of the LIF process, such as saturation or polarization effects, which could alter the results if they were ...
