Experimental Verification of the Mathematical Model for Infrared Multiphoton Dissociation Induced by a Transversely Non-uniform Laser Beam Focused in a Static Gas Cell

Abstract

Multiphoton absorption (MPA) and multiphoton dissociation (MPD) experiments are reported for the C₂ClF₅/O₂ system. The MPD experiment with a focused non-uniform non-Gaussian beam yields a smaller reaction volume than that with a transversely uniform beam. With the mathema-tical model we developed, this difference is explained quantitatively over a wide range of fluences.
