Abstract
A method of energizing a laser source stimulating flash lamp directly from an AC power line. Uncontrolled diodes couple the anode and cathode of the flash lamp directly to the AC line. The lamp is triggered by a separate triggering circuit which produces its trigger pulse at a predetermined phase of the AC power source. The use of high current carrying controlled rectifiers and large energy storage devices is thereby eliminated.
