A method for laser-marking an iron-based sintered body includes a first step of forming with a first laser beam a plurality of dotted recesses with a predetermined depth in an identification mark area of a surface of an iron-based sintered body, and a second step of flattening with a second laser beam the surface within the identification mark area other than the dotted recesses. The first laser beam has an irradiation energy per unit area greater than an irradiation energy per unit area of the second laser beam.

A dimensional lumber product and method for marking them. The lumber is marked on a side at regular intervals. The marks may be made with laser, paint, or mechanical force. The marks enable a builder to make accurate cuts using the existing marks, without needing to measure and manually mark the lumber.

Apparatus and method for using a line laser (LL) to quickly mark a substrate or media by utilizing a laser additive on/within the substrate/media, which greatly reduces the power requirement for marking the substrate/media. The combination of the LL wide swath (>305 mm) and the improved media/surface sensitivity to laser wavelength allows the LL marking system to achieve faster marking than other systems. The LL is mounted over a transport which transports the sensitized substrate/media past the LL for marking. The desired image is projected from the LL line by line in synch with the moving media and once the media passes the beam path of the LL, marking is complete. In this case, the media has been physically-altered via the heat generated by the LL interacting with the photosensitized media and is permanent. A second method would use a photosensitizing agent coated on top of the media to be marked.

A structure that forms a visual representation may include a first outer layer, a second outer layer, and an interlayer being disposed between the first outer layer and the second outer layer. The interlayer may have a first side adjacent to the first outer layer and a second side adjacent to the second outer layer. The interlayer includes a plurality of cuts extending from the first side of the interlayer towards the second side of the interlayer. Each of the plurality of cuts may have an angle with respect to a plane formed by a surface of the first side of the interlayer. Each angle for at least a portion of the plurality of cuts is based on one or more pixel values of at least one image that forms the basis of the visual representation.

A laser processing apparatus includes: a conveyor to convey a container containing a content in a container body in a conveying direction at a predetermined conveying speed; and a light emitter to emit laser light to a predetermined processing region in the container body conveyed in the conveying direction by the conveyor. A frequency of a vibration of the container body conveyed, in which an amplitude of the vibration of the container body is maximized, is v/L or less, where v is the predetermined conveying speed, and L is a length of the predetermined processing region in the conveying direction.

Features relating to a laser etching and/or tag writing machine are provided. The machine may include a tray assembly including a tray and a nest. The tray may hold an array of vaporizer cartridges. The tray may allow for a laser-etching operation to be performed by the machine on at least one or two sides of the vaporizer cartridges held by the tray. The tray may allow for the array of vaporizer cartridges to be rotated at the same time between laser etching operations. The tray may additionally and/or alternatively allow for the machine, such as via an antenna, to write data to an NFC tag of a corresponding vaporizer cartridge before, during, and/or after each laser etching operation.

The present invention relates to a method for marking a container comprising at least a transparent wall comprising the following steps: a) applying at least one spot of ink on an outer surface of said transparent wall, b) heating said transparent wall, c) engraving a data matrix in the spot of ink of said transparent wall. The invention also relates to a marked container and to a method for identifying such a marked container.
