摘要: Laser induced fluorescence detection of reaction products is now a wide-spread technique. When the laser coherence time longer than spent by molecule in beam, saturation effects laser-molecule interaction cannot be described rate equations. In this paper we present simple theoretical description these and detailed experimental verifications. These results are quite important if one wants to derive reliable population measurements from signals case coherent saturation.
