Sugarbeet has a hard time asserting itself against weeds in the field. That's why various partners have joined forces in the project LUM to develop a method for controlling weeds using hoes and lasers for an automated and sustainable weed control.
At the Expo World Exhibition in Dubai, the Laser Zentrum Hannover e.V. is present as a provider of ideas with an exhibit in the German pavilion. The interactive game "Food Farming Laser" by the agency facts and fiction GmbH is designed to introduce visitors to sustainable laser-based agricultural technology.
In eye surgery for cataract, the lens refilling method could allow to maintain or restore the lens's accommodation of the lens, i.e. the ability to adjust its refractive power flexibly. So far, however, this method has not yet been clinically successful. The Laser Zentrum Hannover e.V. (LZH) is now working within a new research project with ROWIAK GmbH to advance the method further.
Welding 3D-printed components with the laser: This is the goal of the scientists at the Institute for Integrated Production Hannover (IPH) gGmbH and the Laser Zentrum Hanno-ver e.V. (LZH). In the new research project "QualLa", they want to develop an expert system that supports small and medium-sized enterprises in optimizing additive manufac-turing processes – so that the printed components can subsequently be welded soundly with the laser.
More and more nuclear power plants are reaching their maximum service life or are decommissioned due to the nuclear phase-out. To reduce the additional effort of water filtration during dismantling, scientists at the Laser Zentrum Hannover e.V. (LZH) have developed and validated a laser-based cutting process. With this method, up to 95 percent less radioactively contaminated secondary waste is released into the water when the reactor vessel internals are cut.
Up to now, oscillator free-electron lasers have only reached emission wavelengths down to 176.4 nanometers. Scientists at Laser Zentrum Hannover e.V. (LZH) have now succeeded in producing optics that allowed physicists at Duke University, USA, to generate wavelength below 170 nanometers.
Instead of using chemical products, in the future, the growth center of weeds is to be lethally damaged through laser radiation. The partners in the EU project WeLASER want to create the basis for this vision. The project brings together research institutions, companies, and non-governmental organizations (NGOs) from the agricultural sector in eight EU countries, including the Laser Zentrum Hannover e.V. (LZH). Over the next three years, the partners want to test a laser system's effectiveness on selected crops.
They are not yet usable as building blocks – but the lanes melted with the laser are a first step towards 3D-printed buildings, landing points, and roads made of moon dust.
Prof. Dr.-Ing. Ludger Overmeyer, member of the Board of Directors of the Laser Zentrum Hannover e.V. (LZH) and Chairman of the Scientific Directorate, has assumed the presidency of the German Scientific Laser Society (WLT) as of January 1st, 2021.
Improving the detection of cancerous cells during surgery – this is the goal of the European research project CARMEN. The research institutes Laser Zentrum Hannover e.V. (LZH) from Germany and Multitel asbl from Belgium work together with companies from both countries, JenLab GmbH, DELTATEC, and LaserSpec, to develop a novel, compact and multimodal imaging system. This could even allow the examination of tissue samples directly during surgery.
When hip prostheses are replaced, the old bone cement in the femur must first be removed – a complicated procedure. The Laser Zentrum Hannover e.V. (LZH) is developing an endoscope-based laser system with which doctors should be able to remove the old cement more gently and with an improved vision.
Grasses such as slender meadow foxtail and windgrass have become an acute problem on agricultural land. In the event of severe infestation, farmers are threatened with having to take agricultural fields out of production altogether. To develop alternatives in the fight against weeds and herbicide resistance, the Laser Zentrum Hannover e.V. (LZH) is now testing a laser-based approach for its practicality.
The spheres appear inconspicuous – but they are unique. They consist of moon dust, molten under moon gravity in the course of the MOONRISE project. The Laser Zentrum Hannover e.V. (LZH) together with the Institute of Space Systems (IRAS) of the Technical University of Braunschweig carried out this unique experiment in the Einstein-Elevator of the Hannover Institute of Technology (HITec) of the Leibniz University Hannover (LUH).
For the first time, scientists at the Laser Zentrum Hannover e.V. (LZH) have succeeded in measuring zinc samples at a pressure of 600 bar using laser-induced breakdown spectroscopy. They were able to show that the LIBS system developed at the LZH is suitable for use in the deep sea at water depths of up to 6,000 meters.
Locating mineral resources on the sea floor has so far been rather expensive. In order to reduce the costs, the LZH is working with eight other European partners to develop a laser-based, autonomous measuring system for underwater use by 2020.
At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
What tomorrow’s monitoring of coating processes might look like will be presented by the Laser Zentrum Hannover e.V. (LZH) at the Optatec 2018 in Frankfurt/Main from May 15th to 17th, 2018, in hall 3 at booth A 58. This year’s three focuses of the LZH are: in-situ particle detection, spectrally high-resolution online monitoring and flexible measurement technology.
On April 16th, 2018, Dr.-Ing. Stefan Kaierle takes over the scientific and technical management of the Laser Zentrum Hannover e.V. (LZH) together with Dr. Dietmar Kracht. He succeeds Prof. Dr.-Ing. Ludger Overmeyer, who becomes Chairman of the Scientific Directorate from Prof. Dr. Wolfgang Ertmer.
Unexploded bombs are and will remain a serious threat to civil security in many parts of the world. To be able to deactivate these bombs more safely in the future, the Laser Zentrum Hannover e.V. (LZH) is working on a laser-based defusing together with the LASER on Demand GmbH and the Kampfmittelräumdienst Hamburg (KRD). At the Hannover Messe 2018 from April 23rd to 27th, the LZH will be showcasing processed bomb shells at the Pavilion of the State of Lower Saxony (hall 2, stand A08).
Under the main topic "Creatively Additive", the Laser Zentrum Hannover e.V. (LZH) will show creative, light-based and convincing solutions for special requirements in the field of additive manufacturing and 3D printing at the Hannover Messe 2018. From April 23rd to 27th, 2018, the LZH can be found at the Pavilion of the State of Lower Saxony in hall 2 at stand A08.
As of April 1st, 2018, Prof. Dr. Detlev Ristau will be appointed to the Scientific Directorate of the Laser Zentrum Hannover e.V. (LZH). His successor as Head of the Laser Components Department is Dr. Lars Jensen.
On January 25th, 2018, about 25 representatives of Lower Saxony's SMEs attended the first event organized by Niedersachsen ADDITIV - Center for Additive Manufacturing at the Hannover Fairgrounds to learn about the basics, the-state-of-the-art and the applications of additive manufacturing processes. In addition to the technical lectures, the focus of the event "Additive Manufacturing: Opportunities for SMEs" event was on the exchange: In four workshops, the participants discussed technological, economic, safety and educational aspects of 3D printing.
