The laser induced decomposition of CF2Cl2, CF2ClCF2Cl, and CHF2Cl was studied by means of CW and TEA CO2 laser resp. The main aspects studied were the channel competitive processes and the relations between the reaction channels and laser energy fluence. The results show that the decomposition channels depend on both laser energy fluences and nature of compounds The laser decomposition of F22 is first order reaction and there is bottle-neck effect in F22 laser induced decomposition
