Abstract
The shock waves generated by an excitation discharge on XeCl- excimer laser have been visualized by a shadowgraph technique. The propagation velocity of the shock waves has been measured by using an image converter camera. The propagation velocity is estimated to be approximately 530 m/s for the shock wave beating between the main electrodes, which persists for a long period between the discharge region. On the other hand, the shock wave propagating along the flow axis, which originates from the boundary between the heated column and non-heated region, propagates initially with the velocity of approximately 730 m/s. It is clearly explained by using a plane blast wave theory that the propagation velocity of this shock wave slightly decreases as the shock wave propagates.
