Claim:
1. A sealed high intensity illumination device configured to receive a laser beam from a laser light source comprising: a sealed chamber configured to contain an ionizable medium, the chamber further comprising: a reflective chamber interior surface further comprising: a substantially elliptical contour having a first elliptical focal region disposed within the chamber and a second elliptical focal region disposed outside the chamber; and an interface surface configured to admit the laser beam into the chamber and to emit high intensity light from the chamber; a folding mirror comprising a first surface and a second surface; and a first lens disposed between the folding mirror and the first elliptical focal region configured to focus the laser beam toward the first elliptical focal region; and wherein the second elliptical focal region is disposed between the first lens and the folding mirror, the elliptical contour is configured to reflect light from the first elliptical focal region through the second elliptical focus region to the folding mirror, and the folding mirror first surface is oriented toward the chamber and is configured to transmit a first wavelength emitted from the chamber and to reflect a second wavelength.
