Abstract: Embodiments are disclosed for apparatus and methods for increasing the reliability of the flash discharge response in pulsed gas discharge lamps. One embodiment includes a system comprising two gas discharge lamps having cathodes and anodes connected in parallel to a common power source. The lamps are alternatingly triggered such that the discharge from a first lamp reduces residual partial ionization of the gas in a second lamp and vice-versa.

Abstract: A gas discharge lamp has a gas and has a cathode, an anode, and an ignition electrode. Individual discharges of a series of lamp discharges are spaced at least one millisecond from each other, and the individual discharges are generated by providing an electrical charge between the cathode and the anode and providing two or more electrical pulses to the ignition electrode. The second and following electrical pulses occur within a predetermined time of the first pulse. The electrical charge between the cathode and anode is of sufficient voltage and current to create an electrical arc between the cathode and the anode with the gas is ionized.
