Furthermore, a method for automated processing at least one substrate (2) containing a dried fluid (21) sample by means of such a system (1; 1′) is provided.

This laser welding device includes a tubular portion. The tubular portion includes a first tubular portion and a second tubular portion. The second tubular portion has a constant cross-sectional shape orthogonal to an irradiation direction along the irradiation direction E. The tubular portion has a predetermined length that is longer than a length of a chamber in the irradiation direction.

A method for marking a location on a surface of a component includes irradiating the location with a first laser beam to create a first mark having a first color. The location defines a normal extending perpendicularly therefrom. The first laser beam is disposed at a first angle relative to the normal. The method also includes irradiating the location with a second laser beam to create a second mark having a second color different than the first color. The second laser beam is disposed at a second angle relative to the normal. The second angle is different than the first angle.

An additive manufacturing apparatus and corresponding method for building an object by layerwise consolidation of material, where the apparatus includes a build enclosure containing a build support for supporting the object during the build, a material source for providing material to selected locations for consolidation, a radiation device for generating and directing radiation to consolidate the material at the selected locations and an acoustic sensing system. The acoustic sensing system may be arranged to detect acoustic signals generated in the build enclosure by consolidation of the material with the radiation. The acoustic sensing system may be a passive acoustic sensing system arranged to detect acoustic signals generated in the build enclosure that are indicative of at least one condition of the building process and/or the object.

A method includes producing a functional structure on an aluminum surface with a local laser treatment of an aluminum surface. The local laser treatment is carried out with a pulsed laser system having a pulse duration of from 10 ns to 100 ns. The average power of the pulsed laser system is less than 5 kW.

Laser ablation and laser processing fume and contaminant capture systems are disclosed herein. An example system includes a housing forming a partial enclosure that is configured to be placed against a target surface, a transparent window being integrated into a top surface of the housing, the transparent window being configured to allow for the transmission of a laser scan pattern to the target surface, and an outlet port for establishing a negative pressure inside the housing. Air is drawn into the housing through a first inlet port, the air carries contaminants created during ablation of the target surface by the laser scan pattern out of the outlet port.

The invention shows a device for producing nanoparticles, the device having a pulsed laser with a scanning device for guiding the beam of the laser over a target that is fixed in a flow-through chamber. The flow-through chamber is reversibly connected to a supply line for carrier fluid, so that the flow-through chamber is exchangeable e.g. for a further flow-through chamber having a different target and/or a different dimensioning.

A method is disclosed for additive manufacturing a three-dimensional object layer-by-layer including depositing a layer of material on a bed surface or a previously deposited layer of the object to form the object layer-by-layer; providing energy to the material after each layer is deposited with the energy being provided by an energy source that forms an energized beam directed at the material; altering a property of a gas surrounding the material and through which the energized beam extends to alter a property of the object constructed from the material; melting the material with the energized beam to form a melted pool of liquefied material; and allowing the material to solidify to bond the material to a previous layer of material of the object.
