New 3D Beam Shaping Methods for Ultrashort-Pulsed Laser Material Processing
Two members of the Holo/Or staff have recently published an article about the potential of new 3D beam shaping techniques to enable more productive ultrashort laser material processing. There is discussion of laser glass cutting of curved surface and with chamfers included, channel writing for micro fluidics, scribing on the inside of tubes and much more.
This article is entitled, “3D beam shaping methods for ultrashort-pulsed laser material processing.”
The abstract for this paper states:
“Ultrashort-pulse (USP) lasers enable micro-level manipulation of material surfaces and work on the bulk of transparent materials with almost no thermal effects. One major bottleneck that is limiting the processing speed with USP lasers is the effective spreading of laser energy in the processed material. Diffractive optical elements (DOE) are a leading method of solving this bottleneck. In this article, we review the concept of 3D diffractive light shaping for USP lasers and show its usefulness in various industrial USP laser applications.”
Holo/Or develops, designs and manufactures diffractive optical elements (DOEs) and micro-optical elements for any wavelength, from DUV to far IV, as well as software/automation solutions for the design.
