Classification: CPC H | IPC H

Claim 0:
1. A positive high-voltage laser, comprising:
a gas storage tube, having a first end comprising a reflecting mirror and a second end comprising a light emitting surface;
a water cooling tube in the gas storage tube; and
a discharge tube inside the water cooling tube, having a third end comprising a first electrode and a fourth end comprising a second electrode, the first and second electrodes being connected to an exterior of the gas storage tube by lead wires; wherein
the discharge tube and the water cooling tube have a space therebetween configured to circulate a liquid,
the water cooling tube is connected to the exterior of the gas storage tube by a water inlet tube and a water outlet tube, the first and second electrodes include a cathode in a cathode chamber at one of the third and fourth ends closest to the light emitting surface, wherein the cathode chamber has an end connected to an inner wall of the gas storage tube; and
the positive high-voltage laser further comprises a spiral gas return tube configured to communicate with the cathode chamber, and an anode circumscribing an outside of the water cooling tube at the other of the third and fourth ends, wherein the anode is in a tube section directly connected to an inside of the gas storage tube.
