摘要: A method of additive manufacture is disclosed. The method can include providing an enclosure surrounding a powder bed and having an atmosphere including helium gas. A high flux laser beam is directed at a defined two dimensional region of the powder bed. Powder is melted and fused within the defined two dimensional region, with less than 50% by weight of the powder particles being displaced into any defined two dimensional region that shares an edge or corner with the defined two dimensional region where powder melting and fusing occurs.

摘要: A method to produce in-situ steam comprising the steps of producing a laser beam in a steam generator segment positioned in a wellbore in a formation; introducing the laser beam to an activated carbon container, where the activated carbon container comprises activated carbon; increasing a temperature of the activated carbon with the laser beam to produce a hot activated carbon; introducing water to the activated carbon container through a water supply line; producing steam in the activated carbon container when the water contacts the hot activated carbon; increasing pressure in the activated carbon container as steam is produced until a pressure set point of an inter-container valve is reached; releasing steam through the inter-container valve to a steam container; increasing a pressure in the steam container until a release set point of one or more release valves is reached; and releasing steam through the release valve to the formation.

摘要: A method is provided for operating a laser system. During an embodiment of this method, inert gas is directed against an object within a cavity of a collection device. An aperture is formed in the object by ablating the object with a laser beam that travels within the cavity and to the object. Byproducts of the ablation are removed from the cavity. During another embodiment of the method, inert gas is pooled against an object and a gas curtain is provided proximate a lens. The object is cut using a laser beam which travels from the lens, through the gas curtain and the pooled inert gas, to the object. Fumes and/or particulates produced by the formation are directed away from the laser beam.

摘要: A method is disclosed for scribing a contained crack or vent in a chemically strengthened glass sheet. The glass has shallow surface regions under compressive stress, bounding a central region under tensile stress. The vent is formed by rapidly bulk-heating the glass, using radiation from a carbon monoxide laser, to a depth just below a surface compressive region and extending marginally into the tensile stress region then rapidly cooling the heated region with a water mist spray. The glass sheet can be subsequently divided along the vent by application of mechanical or thermal stress.
