Abstract: An automatic ignition circuit for a gas laser preferably one having a grounded DC discharge, wherein a voltage multiplier circuit is operatively connected at one end to the secondary winding of a power transformer, for the generation of the high ignition voltage, a relatively high resistance connected to the high voltage end of such circuit operative to connect such end to an electrode of the gas laser defining the discharge section, a relatively low resistance and a diode in series therewith operatively connected to an intermediate point of said multiplier, operative to connect such electrode to said intermediate point, such point being located to provide, during laser operation, a voltage corresponding approximately to the normal operating voltage whereby the high voltage end of said multiplier is operatively shunted to block said high voltage.
