Abstract: An intense ultraviolet radiation source is disclosed that may be operated in substantially any arbitrary gas environment, without regard to a containment envelope for the ultraviolet radiation source. The intense ultraviolet radiation source can be generated by applying a pulsed or continuous electrical discharge to a partially ionized combustion flame via two electrodes. The combustion flame and electrical discharge can be focused, contained, or confined by gas pressure, electric fields, and/or magnetic fields. Optionally, the thermal energy in the flame and the electrical discharge power input may be augmented with an electromagnetic radiation source, such as a radio-frequency induction heater, a laser, or a microwave generator. Impurities may be placed in contact with or added to the fuel and/or the oxidizer to further alter the emitted ultraviolet radiation spectral brightness as needed.
