Numerical study of the discharge spatial characteristics influence on the KrF laser generation

A self-consistent two-dimensional model of the discharge KrF laser on Ne/Kr/F2 gas mixtures is described. The model predictions are compared with the experimental results for a KrF laser with an excitation pulse duration of ~ 30 ns. An agreement within 10% for the discharge current and laser energy...

Beschreibung
Zusammenfassung:A self-consistent two-dimensional model of the discharge KrF laser on Ne/Kr/F2 gas mixtures is described. The model predictions are compared with the experimental results for a KrF laser with an excitation pulse duration of ~ 30 ns. An agreement within 10% for the discharge current and laser energy is obtained. Evolution of the discharge width and of the radiation intensity distribution between the electrodes over the time of a radiation pulse is demonstrated. In addition, the effect of the electrode radii on laser energy is analyzed.
