Power source for an axial-flow CO/sub 2/laser tube
A power device is described for an axial-flow-type CO/sub 2/ laser shell comprising: a high voltage DC power source directly connected to a cathode of the laser shell, in which a discharge for laser pumping takes place, for applying a constant high DC voltage to the cathode; and a high voltage pulse power source connected through a ballast resistance to an anode of the laser shell for applying a high pulse voltage to the anode, the high voltage pulse power source having a DC power circuit, a switching element having a first terminal to receive a command signal instructing switching operation, and second and third terminals connected or disconnected by the switching operation, the second terminal being connected to the DC power circuit and the third terminal being connected to the anode of the laser shell through ballast resistance, and a PWM controller having an output terminal connected to the first terminal of the switching element, for outputting a pulsed voltage with a predetermined repetition frequency and width, as the command signal.
