UT to Develop Ultra-Pure Laser Light

The University of Twente entered a research project called ULTRAPURE, which aims to develop super-stable, ultra-pure laser light, a key technology for next-generation communications, ultra-precise clocks, and future quantum systems. The €3 million ULTRAPURE project is coordinated by TU Braunschweig and is funded by the European Innovation Council.  Read Article 
LEDs Provide Power and Functionality for Sustainable IoT Networks
LEDs Provide Power and Functionality for Sustainable IoT Networks

In the future, LEDs could serve as data transmitters and energy sources in holistic Internet of Things (IoT) networks. The University of Oulu’s professor Marcos Katz leads SUPERIOT, a Horizon Europe project that aims to develop a flexible IoT system based on the dual-mode use of optical and radio communications. The system will be sustainably powered by printed electronic components made from low-cost, bio-friendly materials.  Read Article

Using Laser Welding Process Monitors to Improve Manufacturing Success
Using Laser Welding Process Monitors to Improve Manufacturing Success

Thu, Dec 11, 2025 12:00 PM - 1:00 PM EST
In recent years, advanced laser process monitors have been developed to capture signals that are generated during the welding process. These systems collect real-time data - such as melt pool behavior and plasma emissions - to detect weld defects, parameter deviations, and equipment issues early on. This presentation will introduce attendees to the various types of process monitors available today, the specific defects that they can identify, and the potential advantages of implementing the technology in manufacturing and production environments.

Manufacturing Solutions for Hollow-Core Fibers

Tue, Dec 16, 2025 10:00 AM - 11:00 AM EST
This webinar explores the complete hollow-core fiber manufacturing chain and the Nextrom machinery that enables it. Beginning with preform manufacturing systems, it examines equipment designed to produce high-quality structures for hollow-core geometries. The webinar will then focus on the fiber draw tower, where precise control of furnace temperature, capstan tension, and internal gas pressure is essential. Finally, it will cover how proof testing equipment ensures the mechanical strength and long-term reliability of the hollow-core fiber. Along the way, the webinar will show how Nextrom's advanced process control and automation features improve yield, reduce defects, and enable consistent fiber quality. Presented by Nextrom.
