Abstract

Detailed experimental results of a discharge-excited high-pressure F2 laser are compared with a model prediction. Special emphasis is placed on the output performance of the discharge-pumped F2 laser at extremely high excitation rates (10 approximately 35 MW/cm3) by using high-pressure laser mixtures up to 8 atm. The kinetics model predicts fractional contributions of excited F2 formation channels, relaxation channels, and absorption channels together with the formation and extraction efficiencies at the experimental conditions. Although the only experimental quantity compared with the model prediction is laser output energy, it is enough to obtain a better understanding of major F2 laser kinetics and key issues for improving the efficiency.
