Laser Surface Texturing Using Diffractive Optical Element

In a new article, Holo/Or introduces a simple and universal optical setup design for laser surface texturing (LST) that provides functionality superior to direct laser interference patterning (DLIP). The method requires only a single periodic, diffractive optical element (DOE) and a focusing lens, while enabling unlimited freedom for spatial shaping and amplitude variations. The concept … Continue reading
