At this year's LASER – World of PHOTONICS in Munich from June 26th to June 29th, 2017, the Laser Zentrum Hannover e.V. (LZH) will be presenting the latest research results and services in hall A3 at stand 506. Popular monuments from the skyline of Hannover will be illustrating the core competencies of the LZH.
The focus is on optical components and systems, optical produc-tion technologies as well as on industrial and biomedical optics. Among other things, the LZH will be presenting optics for special applications, compact lasers and the latest developments in the field of laser material processing and quality control. Seven monuments from Hannover will vividly illustrate the LZH’s spectrum of activities. From laser material processing of metals and plastics to additive manufacturing and up to optical coatings, Hannover demonstrates its innovation potential.
At the LASER 2017, the LZH will be presenting additive manufacturing from the macro- to the nanoscale (here: stereolithography).
Optical components and systems
In the field of optical components, the LZH provides customer-specific solutions even for difficult and unusual problems. At the exhibition, among other things, the research institute will show telescope lenses for space applications and miniaturized complex filters. Be it the characterization of optics, coating services or optics coating for research and other purposes, the LZH is the right partner not only at the LASER 2017.
For the first time, this year, the LZH will be presenting a compact laser head for LIDAR1, LIBS2 and material processing that emits high pulse energies at large repetition rates. The passively Q-switched solid-state laser works with a wavelength of 1030 nm and 515 nm. Also for the first time, the LZH shows a fully glass-based cladding light stripper that extracts leakage radiation from optical fibers in a well-targeted way, and pump combiners that deliver pump radiation to fiber lasers monolithically.
Optical production technologies
From wire-based deposition welding with deposition rates of more than 10 kg/h to Selective Laser (Micro-)Melting, stereo-lithography and nozzle-based processes up to Two-Photon-Polymerization – the LZH will be presenting the state-of-the-art in additive manufacturing: from the macro- to the nanoscale.
Another topic in the field of optical production technologies is the use of lasers underwater. At the stand of the LZH, processes for cutting sheet metal and for analyzing material on the seabed will be shown. In the field of lightweight construction, the institute presents adapters made of steel-aluminum for the light-weight ship building of tomorrow. Further exhibits cover an automated glass welding process with filler material as well as a laser-encoded shaft for torque measurement.
Industrial and biomedical optics
In the field of industrial and biomedical optics, this year’s focus is on quality-control with light-based methods. At the exhibition, among other things, the LZH will be demonstrating how the Opti-cal Coherence Tomography can be used for inline quality control during laser transmission welding. The three-dimensional imaging of 3D-printed parts made of plastics using laser grid tomography is suitable for controlling manufacturing results, too.
1 LIDAR (eng.: Light detection and ranging) is an optical method for distance measurement, similar to the radar.
2 LIBS (eng.: Laser Induced Breakdown Spectroscopy) is a method to analyze the composition of a material.

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.

Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.
Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
In the fight against cancer, scientists are developing new drugs to hit tumor cells at so far unused weak points. Such a “sore spot” is the protein complex...
In an article that appears in the journal “Review of Modern Physics”, researchers at the Laboratory for Attosecond Physics (LAP) assess the current state of the field of ultrafast physics and consider its implications for future technologies.
Physicists can now control light in both time and space with hitherto unimagined precision. This is particularly true for the ability to generate ultrashort...
The Atlantic overturning – one of Earth’s most important heat transport systems, pumping warm water northwards and cold water southwards – is weaker today than any time before in more than 1000 years. Sea surface temperature data analysis provides new evidence that this major ocean circulation has slowed down by roughly 15 percent since the middle of the 20th century, according to a study published in the highly renowned journal Nature by an international team of scientists. Human-made climate change is a prime suspect for these worrying observations.
“We detected a specific pattern of ocean cooling south of Greenland and unusual warming off the US coast – which is highly characteristic for a slowdown of the...
