Abstract
The invention provides a discharge electrodes structure which can be easily replaced and adjustable a distance between the discharge electrodes, and a laser apparatus employing the discharge electrodes. Accordingly, the laser apparatus is provided with a pair of anode ( A) and cathode ( B) provided within a laser chamber ( ) for sealing a laser medium in an opposing manner, generating a discharge so as to excite the laser medium and oscillating a laser beam, a conductive anode base ( ) holding the anode, an insulative cathode base ( ) placed so as to close an opening portion ( ) provided in the laser chamber and holding the cathode, a return plate ( ) suspending the anode base from the cathode base so as to supply a current to the anode, and an anode support bar ( ) for connecting the cathode base to the anode base so as to suspend the anode from the cathode base.
