Laser-Interference Structuring System Prepares Surfaces for Protective Coatings
The chemical pre-treatment processes used to prepare U.S. Department of Defense materials for protective coatings involve hazardous compounds. Now, a laser-interference structuring (LIS) system developed by the Department of Energy’s Oak Ridge National Laboratory (ORNL) could make protective coating application safer and more sustainable by lessening the need for these hazardous chemicals.

Raman Imaging for the Complete Polymer Lifecycle: From Materials Science to Environmental Impact
Thu, Oct 14, 2021 10:00 AM - 11:00 AM EDT
Raman imaging microscopy is the ideal tool for investigating polymer products at every stage of their lifecycle. From initial development to production and quality control, throughout use and eventual disposal, Raman spectroscopic characterization enables detailed analyses of polymers that can help optimize formulations and processes. This presentation with Nour Hafi, Ph.D., applications scientist at WITec, will describe relevant variations of Raman imaging and provide examples of their applications in various fields. Presented by WITec GmbH.

Controlling High-Power Laser Processes
Wed, Oct 13, 2021 1:00 PM - 2:00 PM EDT
Laser beams with powers of many tens of kilowatts are becoming increasingly common in today's industrial applications. However, as the powers increase, the stakes increase as well. In this webinar, Mark Slutzki of Ophir will discuss how to monitor appropriate laser parameters to keep high-power processes stable and predictable. Presented by Ophir.
