Pulsed Laser Light for Polishing and Surface Topography Control
WARF: P170116US01

Inventors: Justin Morrow, Frank Pfefferkorn

The Invention
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.
