摘要： An electrodeless laser-driven light source includes a laser that generates a CW sustaining light. A pump laser generates pump light. A Q-switched laser crystal receives the pump light generated by the pump laser and generates pulsed laser light at an output in response to the generated pump light. A first optical element projects the pulsed laser light along a first axis to a breakdown region in a gas-filled bulb comprising an ionizing gas. A second optical element projects the CW sustaining light along a second axis to a CW plasma region in the gas-filled bulb comprising the ionizing gas. A detector detects plasma light generated by a CW plasma and generates a detection signal at an output. A controller generates control signals that control the pump light to the Q-switched laser crystal so as to extinguish the pulsed laser light within a time delay after the detection signal exceeds a threshold level.

摘要： Provided is an excimer lamp light source device that achieves low cost and avoids the occurrence of narrowly-defined contracted discharge by adopting a lamp bulb having a simple structure and of the type in which a discharge current is passed in a tube axis direction.
The excimer lamp light source device includes: an excimer lamp that has a pair of external electrodes configured to induce an electric discharge in a discharge space of a lamp bulb and to cause a discharge current to flow in a tube axis direction of the lamp bulb, and that generates UV light in the discharge space by the discharge; and an inverter having a transformer equipped with a secondary winding to which the external electrodes are connected in order to apply a high-voltage alternating current to the excimer lamp, the inverter supplying power lower than power that causes a linear discharge.

摘要： A device for emitting ultraviolet light includes at least one excimer lamp and a housing for the excimer lamp(s). Each excimer lamp has a discharge vessel filled with light-emitting gases, and a pair of first and second electrodes that are placed in contact with the discharge vessel and produce a dielectric barrier discharge inside the discharge vessel. The housing is made of an insulating and heat-resistant resin material. The housing is configured to house the excimer lamp(s), and has a light-emitting window that allows light with a center wavelength in a range from 200 nm to 230 nm emitted from the excimer lamp(s) to exit from the housing.

摘要： A system for forming a laser-sustained plasma includes a gas containment element, an illumination source configured to generate pump illumination, and a collector element. The gas containment element is configured to contain a volume of a gas mixture. The collector element is configured to focus the pump illumination from the pumping source into the volume of the gas mixture contained within the gas containment element in order to generate a plasma within the volume of the gas mixture that emits broadband radiation. The gas mixture filters one or more selected wavelengths of radiation emitted by the plasma.

摘要： Provided is an excimer lamp having a simple and small structure, which can be used in, for example, a refrigerator, and can emit ultraviolet light at a wavelength effective in disinfection processing without generating ozone in a surrounding atmosphere, without leaving gas impurities and moisture in an electrical discharge vessel, and without causing a steep illuminance decrease. A fluorescent substance is disposed on an inner face of the electrical discharge vessel for converting ultraviolet light emitted upon excimer electrical discharge of a light emitting gas to ultraviolet light having a longer wavelength. An inner electrode has a coil shape. A tight winding portion is formed at a certain area of the interior electrode which extends in the center axial direction of the interior electrode such that the coil is tightly wound in the tight winding portion. A getter is attached to the tight winding portion.
