Diffractive Laser Induced Texturing (DLITe)
Patterning surfaces of different materials has great economic and ecological potential. Products with modified surfaces can have longer lifetimes, improved ease of cleaning and lower friction.
Various application-tailored surface properties, can be easily added to a surface using Laser Surface Texturing (LST) methods. Properties such as tribological functions, hydrophobia, increased light scattering, self-clean, antiseptic properties and more.
The continuously growing availability of laser power enables laser processing of progressively larger areas, while maintaining LST inherent advantages of precision, dry environment, microscale features and geometry flexibility.
Holo/Or’s DLITe was developed to enable such large area processing. DLITe is a new category of diffractive beam splitters, aimed at Diffractive Laser Induce Texturing.
DLITe beam splitters are specially designed diffractive optical elements (DOEs) that shape a high-power laser beam into a precise array of laser spot s. These spots can be gaussian dots, lines or sharp edged flat-top shapes, such as rectangles or squares, with user defined separations between them. DLITe are designed to enable patterning of large areas without any movement of the galvo scanner or stage. They are limited only by laser power and focus optics. The patterned areas can then be stitched together at a high speed by external movement, to achieve industrial processing speeds.

DLITe splitters for laser surface texturing are easy to integrate, requiring a simple optical setup consisting of a laser, the splitter and a focusing lens. They are insensitive to centration and will work well with normal optical tolerances.
DLITe concept for LST has been previously published as a scholarly article here, and was experimentally demonstrated by HiLASE center using their PERLA laser. Initial results are shown on the video to the right.
