Abstract: The kinetic process of photochemical reaction of diazophthopuinon system was studied by laser induced fluorescence attenuation. The nonlinear relation between photodecomposion of the system and laser power was observed and investigated in detail at 457.9 nm laser line. It is found that the final product of the reaction mentioned above strongly fluoresces and that it peaks at 567.0 nm while the diazonaphthoquinon peaks at 589.3 nm.

Key words: laser induced fluorescence attenuation, photochemical reaction
