In an ignition circuit for a split section gas discharge laser having a common anode, a positive sustaining voltage is applied to the common anode while independent negative starting potentials are applied through high resistances to cathodes at either end of the laser tube which are grounded through diodes to prevent shorting of the ignition voltage source while providing a return path for the sustaining voltage source. The cathodes are immediately brought to ground potential upon ignition so that gas discharge in each of the two sections may be independently ignited while mirrors at either end of the laser tube are maintained at or near ground potential during operation of the laser after ignition.
