Abstract
The invention is directed to a sealed high intensity illumination device configured to receive a laser beam from a laser light source. A sealed chamber is configured to contain an ionizable medium. The chamber includes a reflective chamber interior surface having a first parabolic contour and parabolic focal region, a second parabolic contour and parabolic focal region, and an interface surface. An ingress surface is disposed within the interface surface configured to admit the laser beam into the chamber, and an egress surface disposed within the interface surface configured to emit high intensity light from the chamber. The first parabolic contour is configured to reflect light from the first parabolic focal region to the second parabolic contour, and the second parabolic contour is configured to reflect light from the first parabolic contour to the second parabolic focal region.
