Discharge electrodes structure for laser apparatus and laser apparatus therewith

A laser apparatus provided with a discharge electrodes structure comprising:

• a pair of anode and cathode 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 said laser chamber and holding the cathode;
• and
• a return plate suspending said conductive anode base from a ground current supply rod fixed into the insulative cathode base, wherein a current to said anode is supplied through said return plate.
