Abstract
An apparatus and a method for operating a sealed beam lamp containing an ionizable medium are disclosed. The lamp includes a sealed chamber, a pair of ignition electrodes, a substantially flat chamber ingress window, and a laser light source disposed outside the chamber producing laser light. Laser light is focused to a first focal region coinciding with an ignition region disposed between the ignition electrodes. The ionizable medium at the ignition region is ignited with the laser. The laser light is focused to a second focal region coinciding with a plasma sustaining region not co-located with the plasma ignition region.
