| 摘要 |
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 (5A) and cathode (5B) provided within a laser chamber (2) 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 (6) holding the anode, an insulative cathode base (8) placed so as to close an opening portion (4) provided in the laser chamber and holding the cathode, a return plate (9) suspending the anode base from the cathode base so as to supply a current to the anode, and an anode support bar (23) for connecting the cathode base to the anode base so as to suspend the anode from the cathode base.
