Abstract
A method and apparatus for a sealed high intensity illumination device are disclosed. The device is configured to receive a laser beam from a laser light source. The device has a sealed chamber configured to contain an ionizable medium. The chamber has a substantially flat ingress window disposed within a wall of the integral reflective chamber interior surface configured to admit the laser beam into the chamber, a plasma sustaining region, a plasma ignition region, and a high intensity light egress window configured to emit high intensity light from the chamber. The chamber has an integral reflective chamber interior surface configured to reflect high intensity light from the plasma sustaining region to the egress window. There is a direct path of the laser beam from the laser light source through the lens and ingress window to the lens focal region.
