Experimental study on shock waves in a high repitation rate excimer laser has been carried out. In a high repitation rate excimer laser. shock waves in subsonic loop are induced by the active medium excitation by means of pulse discharge. Shock waves in He gas by a pulse discharge are visualized by schlieren method using a scale discharge section model, CCD camera, stroboscope, and digital image memory which used to take photographer. Shock waves from anode surface, cathode surface. discharge region, and pin sparks for preionization are observed. Shock waves reflect at anode and cathode surfaces alternately for several times. Shock waves from dischrage region travel through channel.
