Abstract

Broadband output high power pulsed flash lamps are useful in many applications, including beacons, communications, imaging, laser pumping, and materials processing. When specifically optimized, they can become an excellent source of ultraviolet (UV) light, which is particularly useful for photo-chemically-induced materials processing applications. Ultraviolet lamps producing high power pulsed ultraviolet (PUV) light can be ideally suitable for use in the decontamination of fluids (particularly water, wastewater, and other liquids, gases and objects), and for other applications such as photo-enhancement of chemical reactions, treatment of light sensitive materials, medical use, and so forth. In many operation scenarios the required pulsed energy transfer (high average and/or peak power) and subsequent thermal effects may create certain detrimental effects, such as reduction of lamp efficiency, changes in lamp spectral output, reduction of the delivered radiation due to fouling of optically transmitting surfaces, damage of lamp components, and reduction of lamp service lifetime, thereby requiring the use of an ancillary lamp cooling system. As newly designed flash lamp systems may require performance and power levels that exceed those of the traditional order, the heretofore known cooling methods can be problematic and inadequate for meeting increased requirements of the newest generation of high power pulsed flash lamps. This invention creates several new and advantageous methods to provide the increased cooling performance capabilities dictated by such high power pulsed flash lamps.
