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.

Perfect nanospheres using ultrashort laser pulses

The Nanophotonics Group of the Laser Zentrum Hannover e.V. (LZH) has developed a method to print nanoparticles made of different materials with controlled, reproducible sizes and to precisely deposit these particles on a receiver substrate. As a result, for the first time, the scientists succeeded in generating and positioning perfectly round silicon nanoparticles with a diameter of 165 nm. This method was presented in the March 4th issue of Nature Communications.

Hannover Messe 2014 – Making lightweight construction fit for everyday use

Unfortunately, dents and scratches are part of everyday life, both for cars and for aircraft. Therefore, established repair processes exist for conventional automobiles and aircrafts. For automobiles or aircraft made of lightweight materials, however, very often the damaged parts must be completely replaced. Especially for carbon fiber reinforced plastics (CFRP) there are presently only manual repair methods, making repair too expensive. The scientists of the composites group at the Laser Zentrum Hannover e.V. (LZH) are therefore investigating laser-based repair processes that can be automated, and are thus much more cost-efficient than the existing processes.

Ear implants with a memory

From small plastic manikins to noodles and prototypes for industry – today, 3D printers can print almost everything. The challenge, however, is to print highly precise and small prints which are, on top of that, made of difficult-to-process materials. The scientists at the Laser Zentrum Hannover e.V. (LZH) are conducting research on that very topic. At the Hannover Messe 2014, they will demonstrate how they use the laser to manufacture tiny implants with a memory function or complex shapes, such as the cochlea of the human inner ear.
