摘要： A product having at least one plasma lamp that includes plates that are approximately parallel, with at least one array of microcavities formed in a surface of at least one plate. When desirable, the plates are separated a fixed distance by spacers with at least one spacer being placed near the plate's edge to form a hermetic seal therewith. A gas makes contact with the microcavity array. Electrodes capable of delivering a time-varying voltage are located such that the application of the time-varying voltage interacts with the gas to form a glow discharge plasma in the microcavities and the fixed volume between the plates. The glow discharge plasma efficiently and uniformly emits radiation that is predominantly in the UV/VUV spectral range with at least a portion of the radiation being emitted from the plasma lamp.

摘要： A high brightness laser-sustained broadband light source includes a gas containment structure and a pump laser configured to generate a pump beam including illumination of a wavelength at least proximate to a weak absorption line of a neutral gas contained in the gas containment structure. The broadband light source includes one or more anamorphic illumination optics configured to focus the pump beam into an approximately elliptical beam waist positioned in or proximate to the center of the gas containment structure. The broadband light source includes one or more first collection optics configured to collect broadband radiation emitted by the plasma in a direction substantially aligned with a longer axis of the elliptical beam waist.

摘要： An envelope of an ultraviolet (UV) bulb comprises a tube of UV transmissive material configured to contain a UV emissive material and a plasma resistant coating on an inner surface of the tube wherein the coating has been deposited by atomic layer deposition (ALD) and is the only material attached to the inner surface of the tube. The tube can be an endless tube having a circular shape and the coating can be an ALD aluminum oxide coating. The UV transmissive material can comprise quartz or fused silica and the tube can have a wall thickness of about 1 to about 2 mm. The coating can have a thickness of no greater than about 200 nm such as about 120 nm to 160 nm. The circular tube can be formed into a torus shape which can have an outer diameter of about 200 mm and the tube itself can have an outer diameter of about 30 mm. The ALD aluminum oxide coating can be a pinhole free conformal coating. A UV bulb comprising the envelope can contain mercury and inert gas such as argon with pressure inside the UV bulb below 100 Torr. A method of curing a film on a semiconductor substrate, comprises supporting a semiconductor substrate in a curing chamber and exposing a layer on the semiconductor substrate to UV radiation produced by the UV bulb. Other uses include semiconductor substrate surface cleaning or sterilization of fluids and objects.

摘要： System and/or method generally relate to extending a lifespan of an excimer lamp. The system includes a ultra-violet (UV) light having a pair of dielectrics configured to separate electrodes. One of the electrodes includes a metal mesh. The system includes a power supply electrically coupled to the UV light and configured to deliver electrical power to the UV light. The system includes a temperature sensor operably coupled to the UV light. The temperature sensor is configured to generate a temperature signal indicative of a temperature of the UV light. The system includes at least one processor. The at least one processor is configured to determine a temperature of the UV light based on the temperature signal, and adjust the electrical power delivered to the UV light based on the temperature signal.

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 configured to focus the pump illumination from the pumping source into the volume of the gas mixture in order to generate a plasma within the volume of the gas mixture that emits broadband radiation. The gas containment element may be configured to contain a volume of a gas mixture including a first gas component and a second gas component. The second gas component suppresses at least one of a portion of the broadband radiation associated with the first gas component or radiation by one or more excimers associated with the first gas component from a spectrum of radiation exiting the gas mixture.

摘要： The improvements include an illuminator for a gun comprising a manually manipulated and storable external IR filter with a plurality of radially directed circumferential tabs integrally extending from the frame to allow a manual torque to be applied to the frame to manually screw it into and out of the bezel in the field. A high g-force diaphragm shock mount for the lamp includes a receptacle which positions the longitudinal axis of the lamp on the optical axis of the reflector. The field serviceable lamp assembly is an integrated or modular and sealed unit. A field serviceable electronics module is accessed by removing the rear bezel. The illuminator handle includes a double locked latch lever. A T-Slot to Picatinny adapter allows a SureFire T-rail fitting of the handle to fit a conventional Picatinny rail.

摘要： A laser sustained plasma light source includes a plasma bulb containing a working gas flow driven by an electric current sustained within the plasma bulb. Charged particles are introduced into the working gas of the plasma bulb. An arrangement of electrodes maintained at different voltage levels drive the charged particles through the working gas. The movement of the charged particles within the working gas causes the working gas to flow in the direction of movement of the charged particles by entrainment. The resulting working gas flow increases convection around the plasma and increases laser to plasma interaction. The working gas flow within the plasma bulb can be stabilized and controlled by control of the voltages present on the each of the electrodes. A more stable flow of working gas through the plasma contributes to a more stable plasma shape and position within the plasma bulb.
