Holo/Or DOE Contributes to World Speed Record
HiLASE Centre scientists have broken the world record in the speed production of laser-induced periodic nanostructures on a stainless steel surface. The HiLASE Centre is a part of the Institute of Physics of the CAS. The Laser Micromachining team led by Peter Hauschwitz, applied a concept of multi-beam processing of record speed of 1909 cm2/min to create nanostructures on stainless steel.
The unique combination of HiLASE PERLA ultrashort high-energy pulsed laser system with exceptional beam quality and a novel Diffractive Optical Element (DOE) from the Israeli company Holo/Or are core technologies behind this achievement. The previous world record for nanostructuring, which was held by the Hochschule Mittweida Laser Institute, University of Applied Sciences Mittweida, performs at more than 30% lower processing speed and is based on much more complex and expensive technological solution compared to the new HiLASE solution.
The HiLASE processing technique allows creating Laser-Induced Periodic Surface Structures (LIPSS). LIPSS on stainless steel are important to create anti-bacterial surfaces, friction-reducing surfaces, or surfaces modifying the optical properties of the material. Therefore, the production speed of 1909 cm2/min as well as simplicity and low cost of a new technology are bringing this nano-structuring technology a step closer to wide industrial applications.
