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.

Abstract: Broadband output high power pulsed flash lamps are useful in many applications, and when specifically optimized, can become an excellent source of ultraviolet (UV) light, which is particularly useful for photo-chemically-induced materials processing applications. Multiple factors involved with the production of high-energy light pulses can in certain cases adversely affect the ultraviolet lamp operation, thereby resulting in the development of micro cracks in lamp envelopes and subsequent limitation in lamp lifetime. Similar factors can be responsible for an increased absorption of UV radiation by lamp components and degradation of lamp efficiency. This invention describes new pulsed flash lamp designs that enable a new generation of high power and performance as required by, for example, many large-scale photo-processing applications.
