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.

Process control for fast laser processing of CFRP

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.

Welding thick metal sheets quickly

It is possible to weld thick pipelines and metal sheets made of aluminum alloys or steel at high speeds of 6 m/min. respectively 1.5 m/min. with a hybrid welding process developed at the Laser Zentrum Hannover e.V. (LZH). In the future, the laser-based process can be used to shorten processing times, and thus significantly reduce the processing costs of liquid gas tanks and pipelines.

The LZH develops a fiber amplifier for measuring gravitational waves in space

When the European Space Agency (ESA) sends the “3rd Large Mission” into space in 2034, its goal will be to detect gravitational waves. Scientists at the Laser Zentrum Hannover e. V. (LZH) have now begun to develop fiber amplifiers for the required lasers.
