Analysis of the effect of anhydride of trifluoroacetanhydride in the working mixture composition on the operation of iodine photodissociation laser

The effect of the (CF$_3$CO)$_2$О (trifluoroacetanhydride) buffer additive on the operation of an iodine photodissociation laser is studied experimentally. Comparative experiments for determining the laser energy of the iodine laser with the replacement of the working substance with this buffer additive and without it and with widely used buffer gas SF$_6$ (sulfur hexafluoride) are carried out. Optical inhomogeneities in the working volume, emerging during pumping of working mixtures based on i-C$_3$F$_7$I (perfluoroalkyl iodide) with buffer additives (CF$_3$CO)$_2$О and C$_6$F$_{14}$ (perfluorohexane), are measured. The results of experiments are analyzed.
