ABSTRACT:
A power supply circuit for a gas laser has primary circuitry and secondary circuitry supplied by the primary circuitry. A transformer is positioned between the primary circuitry and a secondary circuitry. Within the secondary circuitry is a spark gap and associated circuitry for creating a voltage buildup to achieve a high ionization voltage required for the laser and for releasing the high ionization voltage in pulses for starting the laser. The circuit further includes laser operating supply circuitry associated with the secondary circuitry and the primary circuitry for supplying the laser at a normal operating voltage much lower than the ionization voltage after the laser has started.
