Laser Development Department
The Laser Development Department concentrates on the development of laser sources for a variety of applications.
Production and systems
The core competencies of the department are laser-based solutions for industrial fields
The main work of the department is in the development of new technologies for the generation of micro- and nano-structured objects ...
The roots of the Laser Component Department go back to the beginning of the 70s
The Biomedical Optics Department combines the use of lasers for imaging, laser surgery, and cell and tissue manipulation.
Materials and Processes
The interaction between the laser beam with mainly metal materials from basic research to industrial contract research
Welcome to the LZH
As an independent non-profit research institute for photonics and laser technology the Laser Zentrum Hannover e.V. (LZH) stands for innovative research, development and consulting. The focus of our applied research in the field of photonic technologies is on:
- Optical components and systems
- Optical production technologies
- Biomedical photonics
Interdisciplinarity is thereby strongly emphasized since the foundation 1986 and is the basis of the excellent work at the LZH. As a reliable partner of the industry, we constantly focus on the customer benefit und use light for innovation.
Laser-gas metal arc (GMA) hybrid welding is fast, good for deep welding, and can be used to bridge large gaps. However, for thicker high-strength, fine-grain structural steels, hot cracks and undesired hardness levels can occur in the welding seam. For this reason, in an interdisciplinary project scientists at the Laser Zentrum Hannover e.V. (LZH) and the Leibniz Universität Hannover (LUH) have developed a hybrid welding system with inductive preheating. This process can be used for reliable, high-quality, single-layer welding of high-strength, fine-grain structural steels up to a thickness of 20 mm.
Successful new forum for optics and photonics: Impact factor of 8.5 for “Light: Science & Applications”
The journal „Light: Science & Applications“ (LSA) was rated with an impact factor of 8.476 by the Journal Citation Report in July. Co-editor in chief Dr.-Ing. Stefan Kaierle, who is also department head at the Laser Zentrum Hannover e.V. (LZH), has been with the open access journal of the Nature Publishing Group (NPG) since its foundation in 2012.
No suitable process control method for laser processing of fiber-reinforced plastics is currently available. Therefore scientists at the Laser Zentrum Hannover e.V. (LZH) are now working together with the Sensortherm GmbH and Newson nv on an innovative combined scanning head: In this head, the beam path of the processing laser is decoupled from the detection beam path used for temperature measurement. This makes it possible to have spatially flexible and temporally high-resolution measurements during the processing of fiber-reinforced plastic.
