A system for generating broadband radiation is disclosed. The system includes a target material source configured to deliver one or more of a liquid or solid state target material to a plasma-forming region of a chamber. The system further includes a pump source configured to generate pump radiation to excite the target material in the plasma forming region of the chamber to generate broadband radiation. The system is further configured to transmit at least a portion of the broadband radiation generated in the plasma-forming region of the chamber out of the chamber through a windowless aperture.

A broadband radiation source is disclosed. The system may include a plasma containment vessel configured to receive laser radiation from a pump source to sustain a plasma within gas flowed through the plasma containment vessel. The plasma containment vessel may be further configured to transmit at least a portion of broadband radiation emitted by the plasma. The system may also include a recirculation gas loop fluidically coupled to the plasma containment vessel. The recirculation gas loop may be configured to transport heated gas from an outlet of the plasma containment vessel, and further configured to transport cooled gas to an inlet of the plasma containment vessel.

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.

A dimmable induction RF fluorescent light bulb comprising a power coupler with reduced extraneous electromagnetic radiation wherein a dimming facility utilizes burst-mode dimming that periodically interrupts the high frequency voltage and current to the power coupler with an off period and an on period in order to reduce the power being delivered to the power coupler wherein the off period is shorter than the time required for an electron density of the discharge within the lamp envelope to substantially decrease.
