The present invention relates to a lamp having synthetic ceramic glass electrodes, which comprises a glass tube, a plurality of synthetic ceramic glass electrodes, and a plurality of connecting members. The plurality of connecting members are disposed between the glass tube and the plurality of synthetic ceramic glass electrodes. The plurality of connecting members have different thermal expansion coefficients. Thereby, by using the plurality of connecting members to connect the plurality of synthetic ceramic glass electrodes, the glass tube and the plurality of synthetic ceramic glass electrodes can be sealed tightly.

An apparatus and a method for operating a sealed high intensity illumination lamp configured to receive a laser beam from a laser light source. The lamp includes a sealed chamber configured to contain an ionizable medium having a plasma sustaining region, and a plasma ignition region. A high intensity light egress window emits high intensity light from the chamber. A substantially flat ingress window located within a wall of the chamber admits the laser beam into the chamber. The lamp includes means for controlled increasing and decreasing a pressure level within the sealed chamber while the lamp is producing the high intensity illumination.
