Surface topography control

Various aspects of the present disclosure are directed toward utilizing pulsed laser light to melt and displace material along a surface. As may be consistent with one or more embodiments, material at respective regions of a surface is melted and displaced using pulsed laser light. The melting and displacement at different ones of the regions is carried out to facilitate different displacement at each region. Such an approach may be used by varying characteristics, such as fluence, of the pulsed laser light at each region. In this contexts, surfaces can be smoothed, and structures can be formed on the surface.

Thin-film devices and fabrication

Thin-film devices, for example electrochromic devices for windows, and methods of manufacturing are described. Particular focus is given to methods of patterning optical devices. Various edge deletion and isolation scribes are performed, for example, to ensure the optical device has appropriate isolation from any edge defects. Methods described herein apply to any thin-film device having one or more material layers sandwiched between two thin film electrical conductor layers. The described methods create novel optical device configurations.

Method for producing a three-dimensional component

A method for producing a three-dimensional component by means of a laser melting process, in which the component is produced by consecutively solidifying individual layers made of building material by melting the building material, wherein said building material can be solidified by the action of radiation, wherein the melting area produced by a punctiform and/or linear energy input is detected by a sensor device and sensor values are derived therefrom in order to evaluate the component quality. The sensor values detected in order to evaluate the component quality are stored together with the coordinate values that locate the sensor values in the component and are displayed by means of a visualization unit in two- and/or multi-dimensional representation with respect to the detection location of the sensor values in the component.
