Apparatus and a method for operating a sealed beam lamp containing an ionizable medium
First Claim
1. A method for operating a sealed beam lamp containing an ionizable medium, the lamp comprising a sealed chamber, a pair of ignition electrodes, a substantially flat chamber ingress window, a laser light source disposed outside the chamber producing laser light, comprising the steps of:
- focusing the laser light to a first focal region coinciding with an ignition region disposed between the ignition electrodes;
igniting the ionizable medium at the ignition region with the laser; and
focusing the laser light to a second focal region coinciding with a plasma sustaining region not co-located with the plasma ignition region.

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.

5. A sealed high intensity illumination system comprising:
-
a laser light source disposed externally to a sealed chamber and configured to direct a laser light beam directly into the sealed chamber; the sealed chamber configured to contain an ionizable medium, the chamber further comprising; a substantially flat ingress window disposed within a wall of an integral reflective chamber interior surface configured to admit the laser beam into the chamber; a first laser light focal region of the laser light source; a second laser light focal region of the laser light source; a high intensity light egress window configured to emit high intensity light from the chamber; the integral reflective chamber interior surface configured to reflect high intensity light from the second laser light focal region to the egress window; and a viewing window disposed within the wall of the integral reflective chamber interior surface. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17)
