Paper Abstract

Shock waves, which are generated by pulsed discharges in excimer lasers, cause a complicated time history of density of laser medium, and successively causing arcing and non- homogeneous excitation in the laser cavity. To clarify the characteristics of the generation and propagation of shock waves by these strong pulse-discharges in an excimer laser, experimental study and numerical analysis using a TVD scheme and Grid-distortion Splitting Method have been carried out. The shock waves are visualized using a CCD color schlieren technique. Numerical calculation by Yee's symmetric TVD scheme is performed for the conditions that corresponds to the experiments. The initial conditions of our calculations are determined by measured results by the laser schlieren method, and from schlieren photographs. The propagation and attenuation of the shock waves in our experimental operation are also visualized from the numerical results and compared to the experimental results.
